The air leaves the fan through the duct at a velocity of 11.25 m/s and a discharge pressure of 7.62cm of water above the atmospheric pressure. If the density of the air is 1.2kg/cu.m and the fan delivers 9.45cu.m/s, what is the fan efficiency when the power input to the fan is 13.75kW at the coupling? Problem No <> A 50kW motor is used to drive a fan that has a total head of 110m. if fan efficiency is 70%, what is the maximum capacity of the fan? Problem No <> A fan is listed having the following performance with standard air: Volume discharge: 120cu.m/s V Speed: 7.0rps V Static pressure: 310mm water gauge V 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. Page 5 I 5 O question.jpg Show all 7:53 AM O Type here to search 81°F Haze 11/18/2021 ... 出
