Question
A wall separated hot water from cold air in order to increase the heat transfer rate a number of fin s are added to air side. The heat transfer coefficient on the water side is 255 W/m K and on the air side is 57 W/m K , the thermal conductivity is 3 W/m.K. The surface area the wall 3 m x 0.6 m and the fin len gth is 125 cm with thickness of 0.5 cm if the number of fins are 96 determine the rate of heat transfer by adding the fins 9:19 PM
