only #7

end of the cab. The bottom of the oil pan is essentially a flat plate that is 12 in. wide and 20 in. long. Oil in the pan is warmed by the engine and, in turn, the heated oil maintains the outside surface of the pan at 130°F. Calculate the heat-transfer rate to the air from the oil parn 7. The fins on an air-cooled motorcycle engine are in essence flat plates 4 cm wide and 14 cm long. For a motorcycle speed of 60 km/hr, determine the heat-transfer rate to the air from one fin. The air temperature is 5°C, and the surface temperature of the fins is constant at 130°C 8, Hvdrogen at 150 K flows past one side of a metal plate that is 1 m long and maintained at a

Explanation / Answer

in this question, you have not mentioned conduction heat transfer coefficient and convection heat transfer coefficient. these are necessary to calculate the parameter 'm' in fin problem. you have also not mentioned the material, if material is given there is a chance to calculate both 'h' & 'k'.
