A fan is to be selected to ventilate a bathroom (dimensions are 2 m x 3 m x 3 m). The air velocity must not exceed 8 m/s to minimize the vibration and noises. The combined efficiency of the fan-motor unit is 50%. If the fan is to replace the entire volume of air in 10 min, compute (a) the wattage of fan-motor unit to be purchased, (b) the diameter of fan casing, and (c) the AP across the fan. Take the air density to be 1.25 kg/m and disregard the effect of the kinetic energy correction factors. 8 m/s Exhaust fan Air A fan is to be selected to ventilate a bathroom (dimensions are 2 m x 3 m x 3 m).
