Q4/ Air at 0°C and 1 atm flows at a velocity of 6 m/s across a rectangular plate at a uniform
temperature of 120 °C. If the dimension of the plate perpendicular to flow is 3 m and
plate in the flow direction is 1.5 m, find:
a) local heat transfer coefficient at the trailing edge
b) the average heat transfer coefficient for the entire plate
c) convective heat transfer from the plate.
