1. What is Well Pump Capacity?

Well pump capacity refers to the total volume of water a pump can deliver over a specific period of time. It's a crucial measurement for determining if a pump meets the water demands of a household or irrigation system.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Q \) — Flow rate in gallons per minute (GPM)
• \( Time \) — Duration in minutes
• \( Capacity \) — Total volume in gallons

Explanation: The formula calculates the total water volume by multiplying the pump's flow rate by the operating time.

3. Importance of Pump Capacity Calculation

Details: Knowing your well pump's capacity helps ensure your water supply meets demand, prevents pump overworking, and aids in proper system sizing and maintenance planning.

4. Using the Calculator

Tips: Enter the pump's flow rate in GPM (usually found in pump specifications) and the desired operating time in minutes. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my pump's flow rate?
A: You can measure it by timing how long it takes to fill a container of known volume (like a 5-gallon bucket) and calculating GPM.

Q2: What's a typical residential well pump capacity?
A: Most household pumps deliver 8-12 GPM, but this varies based on household size and water needs.

Q3: How does pump capacity relate to well recovery rate?
A: Your pump capacity shouldn't exceed your well's recovery rate (how quickly water replenishes) to avoid running dry.

Q4: What affects pump capacity?
A: Factors include pump horsepower, well depth, pipe size, and system pressure settings.

Q5: When should I upgrade my pump?
A: Consider upgrading if your calculated capacity doesn't meet peak demand or if you frequently run out of water.
