(2 points) Flow direction on the gasket side of plate five _________Up________________________ 2.) The walls of a refrigerator are constructed of a layer of fiberglass insulation between two sheet metal panels. Consider a wall with an area of 0.5 m 2 . For the sheet metal (each panel), assume that the thermal conductivity is 75 W/m K and the thickness is 2 mm. For the fiberglass, assume that the thermal conductivity is 0.05 W/m K and the thickness is 25 mm. The air inside the refrigerator is 8 C and the air outside the fridge is 25 C. The convection coefficients inside and outside are 5 W/m 2 K. a.) Using the resistance method, determine the overall heat transfer coefficient (U) for this wall. b.) What is the heat transfer rate in Watts?...
