Mathematics · Fluid Machinery Calculations
Under design conditions, a fan operates at a rotational speed of 30 rps, giving a volume flow rate of 20 m3/s and a static pressure rise of 30 Pa at an air temperature of 15°C, requiring a power input of 1.0 kW. Keeping the speed constant at 30 rps, if the air temperature is increased to 27°C, what will be the new power input to the fan? (Assume ideal gas behavior at constant pressure)
