WebAug 13, 2015 · 1 Answer. Different techniques have been developed to evaluate the efficiency of energy use by a vacuum pump. Most vacuum pump manufacturers catalog their test results, including brake horsepower (actual hp) and cfm vs. vacuum level. Fairly accurate evaluations of power needs can be made from such information sources. Webhorsepower is the minimum power required to move water. In other words, it is the power a pump would require if the pump was 100 percent efficient. The water horsepower can be determined if the flow rate of the water and the force (pressure) required to produce that flow is known. To calculate water horsepower, the following formula can be used.

Webhp x 0.85 (efficiency) = required input 10 hp Rule of thumb: For every 1 HP of drive, the equivalent of 1 GPM @ 1500 PSI can be produced. Rule of thumb: To idle a pump when it is unloaded will require about 5% of its full rated horsepower. Note: 1 hp = 33,000 ft lbs per min or 33,000 lbs raised 1 ft in 1 min 1 hp = 550 ft. lbs. per second 1 hp ... WebPump Horsepower (hp) = flow rate (gpm) x pressure (psi) / 1,714 x pump efficiency factor (Can also use horsepower (hp) = torque (in lbs) x pump speed (rpm) / 63,025) Pump … how to spell walked
