! Required information Air flows in a pipe under fully developed conditions with an average velocity of 1.25 m/s and a temperature of 24°C. The pipe's inner diameter is 4 cm, and its length is 4 m. The first half of the pipe is kept at a constant wall temperature of 100°C. The second half of the pipe is subjected to a constant heat flux of 200 W. The properties of air at 80°C are p = 0.9994 kg/m³, k = 0.02953 W/m-K, v= 2.097 x 10-5 m²/s, cp=1008 J/kg-K, and Pr = 0.7154. NOTE: This is a multi-part question.

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
