The crankcase of an automobile is approximately 30in. long, 12 in. wide, and 4 in deep. assuming that the surface temperature of the crankcase is 160 °f, estimate the rate of heat flow from the crankcase to atmospheric air at 40 °f at a road peed of 60 mph. neglect radiation and use for the front and rear surfaces the same average convective heat transfer coefficient as for the bottom and sides.
