Consider a refrigeration truck traveling at 77mi/h at a location where the air is at 1 atm and 80F. The refrigerated compartment of the truck can be considered to be a 9 -ft-wide, 8-ft-high, and 20-ft-long rectangular box. Assuming the aliflow over the entife outer surface to be turbulent and attached (no flow separation), determine the drag force acting on the top and side surfaces and the power required to overcome this drag. The drag force acting on the top and side surfaces to overcome the drag is ibf: The power required to overcome the drag is kW
