Calculate the convective heat transfer rate via the top and the two side walls of a refrigerated box trailer as shown in the figure. The trailer is cruising at a rate of 70 mph (31.3 m/s). The box trailer dimensions are 16 m long, 4.1 m high, and 2.6 m wide. Assume that the surface of the trailer is at uniform temperature of 10°C. The air temperature is 30°C. Because of the presence of the prime-mover in the front, the air flow can be assumed to be turbulent when it encounters the trailer. 187.4 kW Walls- Prime-mover 16 m 2.6 m

trailer as shown in the figure. The trailer is cruising at a rate of 70 mph (31.3 m/s). The box trailer
dimensions are 16 m long, 4.1 m high, and 2.6 m wide. Assume that the surface of the trailer is at
uniform temperature of 10°C. The air temperature is 30°C. Because of the presence of the prime-mover
in the front, the air flow can be assumed to be turbulent when it encounters the trailer.
