A centrifugal fan is delivering 2000 cfm of air at a total pressure differential of 2 in.w. The fan has an outlet area of 0.85 ft and requires 1.25 hp shaft input power. The fan speed is 1000 rpm. If the fan motor efficiency 85%, calculate: a) The total fan output power (hp) b) The fan total efficiency c) The fan static pressure, in.w
