Consider a room having four identical walls of height 3.2 m and width 4 m each. In a hot summer day, the temperature of the inner surface of each wall is 32oC while the room air temperature is maintained at 24oC. The rate of heat loss from the room through the walls is Properties of the quiescent air: k = 0.0263 W/m.℃, ν = 15.89*10-6 m2/s, alpha= 22.5*10-6 m2/s, Pr = 0.707, β= 1/Tf = 0.00343 K-1. Select one: a. 282.6 W b. 35.3 W c. 1130.5 W d. 141.2 W
