Consider a refrigeration truck traveling at 70 mi/h at a location where the air is at 1 atm and 80°F. 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 airflow over the entire 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.

Question
Consider a refrigeration truck traveling at 70 mi/h
at a location where the air is at 1 atm and 80°F. 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 airflow over the entire 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.
