GPH to PSI Calculator

Calculate PSI from GPH



Formula

The formula to convert GPH to PSI is:

\[ PSI = \left(\frac{\left(\frac{GPH}{60}\right)}{\left(\frac{Area}{144}\right) \times 7.48}\right) \times 0.002228 / 0.433 \]

What is GPH to PSI Conversion?

GPH to PSI conversion is a process of translating the flow rate of a fluid (in gallons per hour) into the equivalent pressure (in pounds per square inch) within a piping system. This conversion is important for engineers and technicians to understand the relationship between the flow of fluid and the pressure it generates, which is crucial for designing and maintaining piping systems and fluid delivery mechanisms.

Example Calculation

Let's consider an example:

Using the formula to calculate PSI:

\[ PSI = \left(\frac{\left(\frac{1200}{60}\right)}{\left(\frac{4}{144}\right) \times 7.48}\right) \times 0.002228 / 0.433 \approx 0.4953 \, \text{PSI} \]

This means that at a flow rate of 1200 GPH and a cross-sectional area of 4 square inches, the pressure generated would be approximately 0.4953 PSI.
