Inputs

The pressure at the exit point should be equal to the atmospheric pressure, i.e., 14.7 psi.

For a cylinder, this is equal to π × (diameter / 2)² .

Results

Enter your values above. The results appear here as soon as there is enough information to calculate them.

How to use the PSI to GPM Calculator

  1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
  2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
  3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
  4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

cross_area = pi × (diameter/2)^2

flow_rate_gpm=sqrt((tank_pressure-exit_pressure)×32.174×144×2/62.4)×cross_area×448.83

Frequently asked questions

What is a PSI to GPM Calculator?

A PSI to GPM calculator is a tool that helps determine the flow rate in gallons per minute (GPM) based on the pressure measured in pounds per square inch (PSI). This conversion is particularly useful in applications such as pressure washing, irrigation, and fluid dynamics.

How do I use the PSI to GPM Calculator?

To use the PSI to GPM calculator, you typically need to input the pressure value in PSI, along with the diameter of the nozzle or pipe through which the fluid will flow. The calculator will then provide the corresponding flow rate in GPM using fluid dynamics equations.

Why is knowing GPM important?

Understanding the flow rate in GPM is essential for several reasons. It helps in selecting the right equipment, optimizing performance, and ensuring that systems function efficiently. For example, in gardening, knowing GPM can help you determine how long to run a sprinkler for adequate watering.

Can I calculate GPM manually?

Yes, you can calculate GPM manually using the formula: GPM = (PSI × Area of the opening) / (Weight of the fluid × 0.433). However, using a calculator can save time and reduce the potential for errors.

Are there any limitations to using a PSI to GPM Calculator?

Yes, the accuracy of a PSI to GPM calculator relies on correct input data and assumptions about fluid properties. Variations in temperature, fluid viscosity, and other factors can affect the actual flow rate. Therefore, the calculator provides estimates rather than precise measurements.
