How to Use the Calculator
- Enter the pipe diameter in inches (e.g., 1.5 for a 1.5-inch pipe).
- Enter the pressure in PSI (pounds per square inch).
- Enter the flow coefficient (Cv), which is a measure of the flow capacity of the valve or pipe.
- Click the "Calculate" button to compute the flow rate in gallons per minute (GPM).
- Click "Reset" to clear all inputs and start over.
Understanding the Formula
The calculator uses the following formula to calculate flow rate:
Q = Cv × √ΔP
Where:
- Q = Flow Rate (GPM) - The amount of water flowing through the pipe per minute.
- Cv = Flow Coefficient - A dimensionless number that represents the volume of water (in US gallons) that will flow through a fully open valve or pipe per minute at a pressure difference of 1 PSI.
- ΔP = Pressure Difference (PSI) - The difference in pressure between the inlet and outlet of the pipe or valve.
Applications
This calculator is useful in various applications, including:
- Plumbing and irrigation systems design
- Water treatment plants
- Industrial fluid flow measurement
- Agricultural systems
