GPM to PSI Calculator

Formula

The formula to calculate the PSI from GPM is:

\[ \text{PSI} = \frac{\text{HP} \times (1714 \times \frac{E}{100})}{\text{GPM}} \]

Where:

\( \text{PSI} \) is the pressure in pounds per square inch
\( \text{HP} \) is the horsepower
\( E \) is the pump efficiency (%)
\( \text{GPM} \) is the flow rate in gallons per minute

What is GPM to PSI?

GPM to PSI is a conversion that helps determine the pressure (PSI) from the flow rate (GPM) in a hydraulic system, factoring in the horsepower and efficiency of the pump. This is crucial for designing and analyzing hydraulic systems to ensure they operate efficiently and effectively.

Example Calculation

Let's assume the following values:

Horsepower (HP) = 10 HP
Efficiency (E) = 85%
Flow Rate (GPM) = 20 GPM

Using the formula to calculate the PSI:

\[ \text{PSI} = \frac{10 \times (1714 \times \frac{85}{100})}{20} = \frac{10 \times 1456.9}{20} = \frac{14569}{20} = 728.45 \]

The Pressure (PSI) is approximately 728.45.
