GPH to PSI Calculator

Formula

The formula to convert GPH to PSI is:

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

Where:

\( PSI \) is the pressure in pounds per square inch
\( GPH \) is the flow rate in gallons per hour
\( Area \) is the cross-sectional area of the pipe in square inches

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:

Flow Rate (GPH): 1200 gallons per hour
Cross-Sectional Area of Pipe: 4 square inches

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.
