1. Power is transmitted through
Power is transmitted through pipes by flowing
water or other liquids flowing through them.
The power transmitted depends upon :
The weight of liquid flowing through the pipe and
the total head available at the end of the pipe.
Consider a pipe AB connected to a tank as shown
in Fig.. The power available at the end B of the
pipe and the condition for maximum transmission
of power will be obtained as mentioned below :

2. L = length of the Pipe,
d = diameter of the pipe,
H = total head available at the inlet of pipe,
V = velocity of flow in pipe,
hf = loss of head due to friction, and
f = co-efficient of friction
