Blower power calculation formula
WebBHP = Q × P / (1714 × n) Where: BHP = Brake Horsepower in Horsepower. Q = Flow Rate in gallons per minute. P = Pressure in pounds per square inch. n = Efficiency expressed as a decimal value*. *Many positive displacement pumps are assumed to operate at 90% efficiency. A value of 0.9 is often used for this calculation. WebApr 19, 2024 · Our most efficient wheel, a backward-curved fan, can achieve 77-80 percent static efficiency. Using the formula, you’ll find that this fan will require about 19.7 horsepower, indicating a 20 horsepower motor, to reach the full performance potential of the volume to static pressure ratio.
