As shown in the figure, air with a volumetric flow rate of 14,000 ft/min enters an air-handling unit at 90°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
Step 1
M₁ =
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 ft/min, and
