An airflow of 500 cfm is discharged at 80 F and a pressure of 0.1 psi gage into a 6 in. square duct located at an elevation of 4 feet. The air flows through ductwork to the top of a 40-foot building where it discharges into the atmosphere through a 12 in. square duct at a temperature of 80 F. Determine the energy loss, head loss, and fan power.\"

Solution

The answer of the following questions are as follows

Energy loss =213.43 J

Head loss = 4.65 f

Fan power =2.4 kPa
