1. Heat and Mass Transfer - Find the answers with a brief explanation.
Heat is lost steadily through a 0.5-cm thick 2 m times 3 m window glass whose thermal
conductivity is 0.7 W/m. degree C. The inner and outer surface temperatures of the glass are
measured to be 12degree C to 9degree C. The rate of heat loss by conduction through the glass is
The heat conduction equation in a medium is given in its simplest form as Select the wrong
statement below. the medium is of cylindrical shape. the thermal conductivity of the medium is
constant. heat transfer through the medium is steady. there is heat generation within the medium.
heat conduction through the medium is one-dimensional.
Solution
v) c 1256w
vi) e) heat conduction through the medium is one dimentional
