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

Hot water is flowing though the center of a AISI 304 stainless steel pipe with a diameter of 300mm, a wall thickness of 10mm and a length of 5m. The pipe is coated with a 2.5mm thick layer of Teflon and covered with a 30mm thick layer of insulation. The water is flowing at a velocity of 0.0015 m/s. Assume the velocity profile to be fully developed. The water is at a temperature of 92°C and the air surrounding the pipe is at 22°C. Some transport properties and dimensions are shown in the table below. 1. What is the heat transfer rate through the pipe and insulation? 2.

In the arctic sea, the ice sheets are melting. Let's calculate the temperautre distribution in one such ice sheet. The sheet is 2 m thick. Under the sheet there is ice-water mixture and it can be assumed that the temperature of the bottom surface of the ice sheet is approximately 0°C. Air at -20°C is blowing above the sheet. The convection coefficient of air is 15 W/m².K. The thermal conductivity of ice is 2.2 W/m.K. What is the temperautre of icesheet at its center (i.e., at 1 m from the surface)?
The main body of plenum is a steel vessel of diameter 0.1meters has two semicircle domed ends. During operation is will contain mix of fuel and air at approximately 250OC. The wall of the vessel is 0.03meters thick and the plenum is 0.45meters long. Estimate the rate of heat loss from the vessel when the outside air temperature is 45OC. The thermal conductivity of steel is 45 W/m K and the surface heat transfer coefficient on the air side is 8 W/m2 . On the inside it is 65W/m2 . If it was possible to clad the plenum calculate the reduction in the rate of heat loss. Assume the lagging would be 5mm thick and has a thermal conductivity of 0.05 W/m.
