Q4-
The wall of a liquid-to-gas heat exchanger has a surface
area on the liquid side of 1.8m^(2)(0.6m\times 3.0m) with a
heat transfer coefficient of 255(W)/(m^(2))Kk=3(W)/(m)K 57(W)/(m^(2))K. Assuming that the thermal resist-
ance of the wall is negligible, determine the rate of heat
transfer if the overall temperature difference is 38\deg C.
