1. INTRODUCTION
Wind power technology dates back many centuries. There are historical claims that
windmachines which harness the power of the wind date back beyond the time of the ancient
Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst theBabylonian
emperor, Hammurabi, used windmills for an ambitious irrigation project as earlyas the 17th century
BC. The Persians built windmills in the 7th century AD for milling andirrigation and rustic mills
similar to these early vertical axis designs can still be found in theregion today. Harnessing
renewable energy is important for conservation of the fossil fuels and reducing environmental
pollution[1].
Wind energy is the kinetic energy associated with the movement of atmospheric air (wind).
Wind is free, clean, and inexhaustible energy source. It has been used for hundreds of years for
sailing, grinding grain, and for irrigation. Wind energy systems convert this kinetic energy to more
useful forms of power. Wind energy systems for irrigation and milling have been in use since ancient
times and since the beginning of the 20th century. It is being used to generate electric power.

Windmills for water pumping have been installed in many countries particularly in the rural areas.
Wind energy is now a low cost generation technology, and it is likely to provide 10 % of the world's
electricity by the year 2020 [2].
The geography of Iraq is diverse. It falls into four main regions: the desert (west of the
Euphrates), Upper Mesopotamia (between the upper Tigris and Euphrates rivers), the northern
highlands of Iraqi Kurdistan, and Lower Mesopotamia, the alluvial plain extending from around
Tikrit to the Arabian Gulf, the agriculture in Iraqis concentrated the alluvial plane from the ancient
times until this moment in.Both the 1991 Gulf war and 2003 Iraq war have effected and used the
water resources. The farmer of Iraq needed water for irrigated the plant, and the electric power
generated is not enough to meet the power demand of irrigation. Renewable energy has played an
important role to meet increasing energy demand especially in the desert and rural communities.In
Iraq, there are many regions that have the range of wind speed of (2-3.5 m/s) which isconsidered
useful for the application of wind energy [3] also these regions are more suited for theutilization,due
to their remoteness and relatively small and scattered population.According to the decreasing of the
conventional energy resources combined with theirecological consequences we must initiate a broad
development program and make substantialfunds for utilizing the renewable energy resources like
solar and wind energy. In Iraq, a lot of works has been done in this field, Al-alawy studied et. al [4]
the possibility of using the wind energy for pumping in some location in the west of Iraq. Erzouky[5]
progress an experimental study for using wind energy for irrigation in Basrah south of Iraq. He used
Svanoius turbine type on the height of 6 m and connected to the water pump. He found the
performance of the system in practice and theoretically and there was a consensus among the results.
Jassem [6] estimated the planted area by using wind energy, also it is found that the maximum area
that can be planted by beans equals 262 m2
for turbine diameter equal 6 m, and pressure head equal
40 m.
This paper aims to secure the needed water andelectricity for people in remote areas for
different locations in Iraq; encouraging the use of renewable energyresources, demonstrate the
economic feasibility and technical viability of wind energysystems, and gain experience in addition
to applied research and development in thefield of wind energy. This research can be considered as a
base of wind energy application in Iraq.
2. WIND ANALYSIS
Wind speed in any region is not constant, but varies over periods of variation, seasonal
variation and yearly variation. The key wind parameter is the mean hub height wind speed. This is
the most significant measure of the quality of the wind resource at the site, and is the main
determinant of how productive a particular wind will be at the site. The mean wind speed over a
period of time is obtained by adding numerous readings taken over that period and dividing the sum
by the number of readings.Wind average or mean wind speed or resultant wind is:
ࢂഥ ൌ
૚
ࡺ
∑ ࢂ࢏
ࡺ
࢏ୀ૚ ……. (1)
Where:
N is the sample size, and Vi is the wind speed recorded for the࢏࢚ࢎ
observation.
In order to take into account the variation in the air massdensity, which is also a parameter
(although of second order) in the wind powerdensity. Therefore, a better method of processing wind
speed data for power calculationsis to digitize the yearly average power density as:

Where: V = wind speed (m/s), A = Rotor area (m2

) at 15 Co

The total power of a wind stream in eq. (4) is directly proportional to its density, area, and the
cube of it velocity. It will shortly be apparent that the total power discussed above cannot all be
converted to mechanical power. In other hand, a wind power is capable of converting no more than
60 percent of the total power of a wind to useful power. The real efficiency (η) is the ratio of actual
to total power, therefore the eq. (4) becomes:
ܲܽܿ‫݈ܽݑݐ‬ ൌ ‫݌ܥ‬ ‫כ‬ 1/2 ߩ‫ܸܣ‬3
…...….. (5)
Where Cp varies between 30 and 40 percent for real turbine.
Fig. (2) shows the rotor efficiency versus tip speed. Rotor efficiency is the fractionof
available wind power extracted by the rotor and fed to the electrical generator.In most of the
meteorological stations, on the whole wind speed is recorded at 10 meters height above the ground.
Since wind turbine hub height are typically between 30 and 50 meters, extrapolation of wind speed
to the planned hub height is usually required to estimate wind potential. Many techniques and models
have been established for height extrapolation of wind speed, the most important and widely used
models are the power law models. Mean monthly wind speed at 50 m height is calculated using the
following power model:

Where Za is the anemometer height, Zh is a common hub height. And the exponent α characterizes
the amount of wind shear and is a function of the surface roughness and terrain features up wind of
the measuring site. It is considered to be variable with the measured wind speed Va and the
anemometer height according to the relationship [12]:

3. WATER REQUIREMENT
The majority of irrigation pumping in Iraq uses fossil fuels such as diesel. An
increasingpercentage of irrigation pumping is however done by usingelectrical energy (42% at
present). High fuel cost is helping to drivethe installed pumping systems to become electric. Wind
power as asource for irrigation Iraq and the decreasing costs of wind energy[7]. In dry climates
conditions and semi-arid regions such as Iraq, where the scarce rainfall and limited irrigation
water,from that require utilization of available water, such as groundwater from wells.To calculate
the amount of water needs from wells we used the following procedures:
3-1 Irrigation
The amount of water sufficient to grew specific crop is very important for the design of any
irrigation project. And there are many factors which effect to the water amount, and they are
sufficient to grow each plant which it are [6]:
1. Irrigation method which will use.
2. Required interval to grew specific crop.
3. Area that covered by water.
4. The characteristics of the soil
5. Irrigation efficiency.
6. Climatic conditions include temperature, relative humidity and wind speed and the amount of
rain and the intensity of radiation and the brightness of the sun, and others.
Al-Latif and Hadithi [8] put tables to show the requirement of each crop to water for middle
of IRAQ (in millimeter per unit area) as shown in Table(1). In order to make the estimate for water
demand, each user's consumptions is identified and summed to find the total. It is desirable to do this
on monthly basis so that the demand can be conveniently related to the wind sources.

3-2 Drinking water
The amount of water sufficient for different species is shown in table.(2)[4] Table.(2) offers
guidelines for estimating the waterrequirements for people and livestock. To estimate the total water
requirements perday, multiply the number of people or animalsby the amount of water they are
expected to consume each day.
Table (2): Water requirements in gallons per day for different species
Species Gallons per day
Human 100 per person
Beef cattle 7-12 per head
Dairy 10-16 per head
Horses 8-12 per head
Sheep and goats 1-4 per head
Chickens 8-10 per 100 birds
Turkeys 10-15 per 100 birds
4. WATER-PUMPING POWER
The power required to pump the water is proportional to its density. The acceleration of
gravity, the total pumping head, and the volume flow rate of water. The power required to left the
water from the well is given by the following equation:
pump
w gQH
P
η
ρ
= …..(8)
Where :P = Power (W), Q = Volumetric flow rate of water (m3
), H = total pumping depth (well
depth + 20 m for losses of water pipes and later tank), ߟpump= Pump mechanical efficiency depended
on the type of the pump and wind velocity as shown in Fig.(2).
For any given wind speed, the power from the rotor must be match the pumping power. Therefore:

5. CALCULATIONS AND RESULTS
5.1 Distribution of wind farms in Iraq
To apply the distribution of the wind farms along the country measurements for the average
wind speed (monthly and annually) in some areas must be studied to give the appropriate decision of
choosing the suitable areas for this purpose. Table-1 gives the actual wind speed(m/s) in Iraqi
governorates for the period of (1981-2000)[12].The data for this study, weregathered at 17 sites; by
the Iraqi MeteorologicalOrganization and Seismology.Inthis type of study longperiod measurements
are needed for a good wind energy assessment. Hence the data collectedcould be used for a
preliminary analysis frequencies of a certain wind speed as well as the monthly andannual mean
wind speeds, to bring out useful conclusions on the wind regime characteristics of thisregion. This
can be done by maintained anemometer coupled to an electronic data-logger, through that allthe
anemometers were mounted on a fixed height above the ground, usually 10m.Fig.(3) shows mean
annual wind speed (m/s) in Iraq, it shows that the wind speed increased gradually from north to the
south of the Iraq. The maximum wind speed was (4 .4 m/s) and recorded at Nasria city in the south
of Iraq. The low wind speed in the north area of Iraq because of this area is considered transition
zone because it locates between mountain in the extreme north east and the opening plains in the
south, this may be consideredas the most promising locations where wind machines canbe installed.
5.2 Estimating the type of the pump:
From the Table.(3), its showed that the wind speed in Iraq is ranging from (1.3 to 4.4 m/s),
according to Fig.(1) the best type of wind turbine is American multi blade type for this range of wind
speed as showed in Fig.(4).
This windmill has dependably provided significant amounts of water, serving the needs of
farmswith only minimal attention for over 150 years. First designed in the mid 1800's, the traditional
Americanwindmill has been improved with countless innovations and is now a highly refined and
successful technology that isonly slightly reminiscent of it predecessors. This type of windmill is
able to pump sufficient amounts of water as it lifts water economically to elevations greater than
(400 m). According to the prevailing wind speed in Iraq, the piston pump is the best for pumping the
water in Iraq as shown from Fig.(2). To calculate the water pumping needs, first estimate how far
water must be lifted fromunderground (the depth of the well) and how much water will be used each
day. Fig.(5) was achieved by using eq.(10), this Figure showed daily water production (Liters) at
well depth was 20 m and this productivity was increased by the increased the diameter of wind
turbine, also the maximum productivity was recorded in Nasria city because the higher value of wind
speed in this location. The lower water productivity was recorded in Mosul city consequence of low
wind speed in this city. The increased in the well depth cause reduction in water production as shown
in Fig.(6,7), In Nasria city, the daily water productivity was decreased from 80000 liters at 20 m
depth of the well to 27000 liters at 60 m well depth. Fig.(8) showed this decreasing in water
productivity clearly as result of the increasing in well depth for different Iraqi towns.
5.3 Monthly water production
Wind is a form of solar energy. It is caused by uneven heating ofthe atmosphere by the sun,
irregularities of the earth’s surface, androtation of the earth. The wind speed different from month to
other throughout the year.The monthly average data obtained from the mentioned source can be
usedfurther to find the monthly water production distribution throughout the year for Baghdad,Nasria
and Mosul are illustrated inFig.(9).It can be seen fromFig.(9) that the highest average water
production values occurs during March up to Septemberand it becomes maximum during July-
August, and September.The higher average wind speed in summer months is very beneficial because

68
the higher water consumption occurred in the summer months for irrigation and drinking. The crop
requires most irrigationwater during summer time (June, July and August).

5.4 Estimating the type of the crops
Table (4) shows the area, which can be planted in (m2
) by different crops for different in Iraq
after connected the pump to a storage tank for one year and using a single wind turbine. The area can
plant depending on the type of plant and the wind characteristics of wind of region. The largest area
was in the Nasria city because of the high level of wind speed in this region, also the increased of
area can be achieved by increase of wind turbine in the location of farmer. For increasing the
planting area by using the modern method in irrigation such as drip Irrigation, Drip irrigation is a
controlled method of irrigation or is a watering method whichdelivers water to plant slowly and right
where they need it. The important advantage is Water saving.All of wind data were recorded at 10 m,
in order to increase the area of planting crops. We can increase the height of the wind turbine to high
altitude. The corrected values at 50 m the tower height are shown in table.(3) according to the eq.(6).

6. CONCLUSION AND RECOMMENDATION
In the present research, the assessment study of the wind potential energy for irrigation in
Iraq leads to the following conclusions:
• Wind energy can be used for planting some of the crops in Iraq.
• The water production can be increased by using the largest wind turbine and increasing the
number of wind turbine can be installed in the site.
• Increasing the well depth reduce the water quantity which can be lift from the well.
