WebView the full answer. Transcribed image text: 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 ... WebNo air conditioning or ventilation ducts shall penetrate separating walls. Diagram 7.1.1(g) In terrace shophouses, the separating walls are also compartment walls, hence, there should be no sharing of air-con ducts. In Commercial Complexes where shops/offices are located, the separating wall
