As shown in the figure, air with a volumetric flow rate of 14,000 ft/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. 4+D - 50 in. Duct T2 = 13 = 1 = 45°F D, = D, = 26 in. V2 = V3 system Air-handling unit

Question
As shown in the figure, air with a volumetric flow rate of 14,000 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. Da = 50 in. %3D Duct T2 = 13 = 1 = 45°F D; = D, = 26 in. V2 = V3 system Air-handling unit 1+ P = P2 = Pa = P4 = 1 atm T = B0°F (AV), Determine the mass flow rate of air entering the air-handling unit, in Ib/s, the volumetric flow rate in each 26-in. duct, in ft/min, and the velocity in the 50-in. duct, in ft/s. 2-
