1. What is Submersible Well Pump Capacity?

Submersible well pump capacity refers to the total volume of water a pump can deliver over a specific period of time. It's typically measured in gallons and is calculated by multiplying the flow rate (GPM) by the operating time.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Q \) — Flow rate in gallons per minute (GPM)
• \( Time \) — Operating time in minutes

Explanation: This calculation gives the total water volume the pump can deliver during continuous operation at the specified flow rate.

3. Importance of Pump Capacity Calculation

Details: Knowing your pump's capacity helps in determining water storage needs, irrigation planning, and ensuring adequate water supply for household or agricultural use.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How do I find my pump's flow rate?
A: Check the pump specifications, or measure it by timing how long it takes to fill a container of known volume.

Q2: What's a typical flow rate for residential well pumps?
A: Most residential pumps deliver between 5-20 GPM, depending on household size and water needs.

Q3: Does pipe size affect capacity?
A: Pipe size affects flow rate (Q), which directly impacts capacity. Smaller pipes may reduce the effective flow rate.

Q4: How does pump depth affect capacity?
A: Deeper wells may reduce flow rate due to increased head pressure, which would decrease capacity over time.

Q5: Can I use this for irrigation planning?
A: Yes, this calculation helps determine how much water you can deliver to your irrigation system over a given time period.
