1. The 4.00mm thick glass windows of an automobile have a surface area of 2.60m². The outside air temperature is 32.0° C. The air in the passenger compartment is maintained at 22.0° C. The convection heat transfer coefficient on the exterior window surface is 90.0W per square meter degree C.

a. Determine the heat transfer through the windows when the interior convection heat transfer coefficient is 15 W per meter squared degree C.

b. By controlling the airflow in the passenger compartment,the interior air heat transfer coefficient can be reduced to 5.00W per meter squared degree C without sacrificing passenger comfort. Determine the heat gain through the windows for the reduced inside heat transfer coefficient.

Consider the vertical rear window of an automobile that has a thickness L= 9 mm and height H=0.5 m with heating wires that create uniform volumetric heating. The window interior is exposed to ambient air at 10°C and the window exterior to air at -10°C which moves in parallel flow over the surface with a velocity of 20 m/s. The surface temperature of the window exterior is 12°C. Using the correlation developed by Churchill and Chu, find the convective heat...

A 3-m-internal-diameter spherical tank made of 1-cm-thick stainless steel is used to store iced water at 0°C. The tank is located outdoors at 18°C. Assume the entire steel tank to be at 0°C and thus the thermal resistance of the tank to be negligible. The heat of fusion of water at atmospheric pressure is hif = 333.7 kJ/kg. The emissivity of the outer surface of the tank is 0.75, and the convection heat transfer coefficient on the outer surface can...
