# How do you convert horsepower to PSI?

**psi**. For the example, the amount in

**psi**is 400. That multiplied by 20 gpm equals 8,000. Divide that number by 1,714 to obtain the hydraulic

**horsepower**.

Herein, how do you calculate horsepower from flow and pressure?

For every 1 **hp** of drive, the equivalent of 1 gpm @ 1500 psi can be produced.

Cylinder Speed - v | (Feet / sec.) = (231 x Flow Rate (gpm)) / (12 x 60 x Area) | v = (0.3208 x gpm) / A |

Secondly, how much horsepower do you need to run a hydraulic pump? 1 **HP** is required for each 1 GPM at 1500 PSI or any multiple of 1500 such as 3 GPM at 500 PSI, 2 GPM at 750 PSI, 1/2 GPM at 3000 PSI, etc. Another handy rule-of-thumb is that it takes about 5% of the **pump** maximum rated **HP** to drive the **pump** when unloaded and pressure is very low.

Correspondingly, how much HP will 5 psi add?

air pressure is 14.7 **psi**. **5** lb boost makes that 19.7, a 34% increase. BEst case scenario is that you **would** gain 34% **horsepower**.

How do you calculate PSI?

Question: - “How do you **find** pounds per square inch (**psi**)?” Divide the pounds of perpendicular force by the square inches of area on which it is acting to get the pressure or stress in pounds per square inch.
