Question

Consider the duct shown in figure with X = 12 meters, Y = 6 meters ,and Z = 12 meters. The duct is used to provide a volumetric flow rate of 0.2 m3/s to a conditioned space from Plenum. There exist a constant pressure drop of 5 Pa in the diffuser. Using equal-friction method and determine the following: 1. Duct diameter 2. Total pressure required at the Plenum 3. Flow velocity in the duct Submit Duct Sizing Chart along with your solution. (Hint: Start solving by assuming pressure drop per unit length of 0.5 Pa/m)
