A centrifugal fan has an inlet duct of diameter 0.60m and a rectangular outlet of cross section 0.5m by 0.4m. At standard air conditions the static depression at fan inlet is 27mm of water and the static pressure at fan discharge is 15mm of water. The mean velocity pressure or dynamic pressure in the discharge duct is 16mm of water column. The electric motor driving the fan consumes 1.5kW and its efficiency is 78%.
Calculate the volume flow of air, and the fan total pressure, static pressure and efficiency.

Consider a centrifugal fan connected to a duct system in an HVAC installation. The intended air flow is 6,000 L/s (6.0 m/s). The fan is driven by a belt-drive and motor. The efficiency of the motor is approximately constant at 91%, and the combined-efficiency of the drive and motor is approximately constant at 87%. fan air filter After the fan is initially installed, it is operated at fan-shaft speed = 1150 rpm. The measured air flow is 6,400 L/s and...
