A fan is listed having the following performance with standard air: Volume discharge: 120cu.m/s Speed: 7.0rps Static pressure: 310mm water gauge BP required: 620kW The system duct will remain the same and the fan will discharge the same volume of 120cu.m/s of air at 93degreeC and a barometric pressure of 735mmHg, when its speed is 7.0rps. Find the brake power input of the fan and the static pressure required.
