CONVERSION
PSI to GPM Calculator
Convert pressure in PSI to flow rate in GPM with our easy-to-use calculator.
What is the PSI to GPM Calculator & How does it work?
Pressure and flow rate are fundamental concepts in fluid dynamics, often encountered in various engineering applications. Pressure (PSI) measures the force exerted per unit area, while flow rate (GPM) indicates the volume of fluid moving through a system per unit time.
The relationship between PSI and GPM depends on several factors, including pipe diameter, fluid viscosity, and length. However, for a simplified conversion, we can use an empirical formula that approximates this relationship under certain conditions.

GPM = C times sqrt{PSI}
C = a constant factor depending on the specific system parameters

Frequently Asked Questions
How do I convert PSI to GPM?
To convert PSI to GPM, you need to know the pipe diameter and length. Use an empirical formula or consult a flow rate chart specific to your fluid.
What factors affect the conversion from PSI to GPM?
Factors include pipe diameter, fluid viscosity, pipe length, and any fittings or valves in the system.
Can I use this calculator for gases as well?
This calculator is primarily for liquids. For gases, different formulas and considerations apply due to varying compressibility.
What is the relationship between PSI and GPM?
PSI (pounds per square inch) measures pressure, while GPM (gallons per minute) measures flow rate. They are related through fluid dynamics equations that consider pipe characteristics and fluid properties.
How accurate is the conversion from PSI to GPM?
The accuracy depends on the assumptions made in the empirical formula or chart used. It’s most accurate for steady, laminar flow conditions.
Is there a specific formula I should use for this conversion?
A common formula is Q = C * A * sqrt(2 * g * h), where Q is flow rate (GPM), C is the discharge coefficient, A is the cross-sectional area of the pipe, g is acceleration due to gravity, and h is head loss.
Can I use this calculator for high-pressure systems?
For very high-pressure systems, consider using more detailed fluid dynamics software or consulting with a professional engineer to account for complex flow behaviors.
