1. What is GPM in Water Pumps?

GPM (Gallons Per Minute) is a measurement of flow rate that indicates how many gallons of liquid pass by a specific point within one minute. It's a crucial specification for water pumps in various applications.

2. How Does the Calculator Work?

The calculator uses the GPM formula:

Where:

• \( GPM \) — Gallons per minute
• \( Q \) — Flow rate in cubic meters per second (m³/s)
• \( 15850.32 \) — Conversion factor from m³/s to GPM

Explanation: This conversion allows you to calculate the flow rate in gallons per minute when you know the flow rate in cubic meters per second.

3. Importance of GPM Calculation

Details: Knowing the GPM of a water pump is essential for proper system design, ensuring adequate water supply, and selecting the right pump for your needs.

4. Using the Calculator

Tips: Enter the flow rate in cubic meters per second (m³/s). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert from m³/s to GPM?
A: While m³/s is a standard SI unit, GPM is commonly used in many industries, especially in the US, for specifying pump capacities.

Q2: What is a good GPM for a residential water pump?
A: Typical residential pumps range from 6-12 GPM, but requirements vary based on household size and water usage patterns.

Q3: How does GPM relate to pump pressure?
A: GPM and pressure (PSI) are related through the pump's performance curve - generally, as flow increases, pressure decreases.

Q4: Can I use this for other liquids besides water?
A: Yes, but the actual flow rate may vary slightly depending on the liquid's viscosity and density.

Q5: How accurate is this conversion?
A: The conversion factor is mathematically precise, but actual pump performance may vary based on system conditions.
