As shown in the figure, air with a volumetric flow rate of 17,000 ft3/min enters an air-handling unit at 80°F, 1 atm. The air-handling unit delivers air at 45°F, 1 atm to a duct system with three branches consisting of two 26-in.-diameter ducts and one 50-in. duct. The velocity in each 26-in. duct is 10 ft/s. Assume steady state operation and ideal gas behavior for the air.
