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 16 ft/s. Assume steady state operation and ideal gas behavior for the air. T₂ = 73 = T₁=45°F D₂-D₂ = 26 in. V₂ = V3 -D4= = 50 in. Duct system Air-handling unit 3 1- P₁ = P₂ = P3 = P4 = 1 atm T₁ = 80°F (AV)₁ Determine the mass flow rate of air entering the air-handling unit, in lb/s, the volumetric flow rate in each 26-in. duct, in ft³/min, and the velocity in the 50-in. duct, in ft/s.
