Air at 1 atm and 60°F is flowing through a 1 ft x 1 ft square duct made of commercial steel at a rate of 1300 cfm. Determine the pressure drop and head loss per ft of the duct. Take the density and dynamic viscosity of air at 1 atm and 60°F as p= 0.07633 lbm/ft³, p = 0.04365 lbm/ft-h, and v=0.5718 ft²/hr = 1.588 x 10-4 ft²/s. The roughness of commercial steel surfaces is ε = 0.00015 ft. 1 ft Air 1 ft The pressure drop is lbf/ft². The head loss per feet of the duct is ft.
