13 30 points Check my work Consider a refrigeration truck traveling at 72 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. eBook Hint Print References Air, 80°F V = V mi/h 2011 8ft Refrigeration truck The drag force acting on the top and side surfaces to overcome the drag is 59.269 lbf. The power required to overcome the drag is 8.484 kW. < Prev 13 of 21 Next > 1
