4 12 WP As shown in Fig P4 12 air with a volumetric flow rate of 15 000 ft min enters an air handling unit at 35 F 1 atm The air handling unit delivers air at 80 F 1 atm to a duct system with three branches consisting of two 26 in diameter ducts and one 50 in duct The ve locity in each 26 in duct is 10 ft s Assuming ideal gas behavior for the air determine at steady state a the mass flow rate of air entering the air handling unit in lb s b the volumetric flow rate in each 26 in duct in ft min c the velocity in the 50 in duct in ft s ans 20 lb s 2210 ft 3 min 14 6 ft s
