1. What is Submersible Pump Capacity?

Submersible pump capacity represents the total output capability of a pump, calculated as the product of flow rate and head. It indicates the pump's ability to move fluid against resistance.

2. How Does the Calculator Work?

The calculator uses the capacity formula:

Where:

• \( Flow\_Rate \) — Flow rate in gallons per minute (gpm)
• \( Head \) — Total dynamic head in feet (ft)

Explanation: The formula calculates the pump's total capacity by multiplying the flow rate by the head the pump can generate.

3. Importance of Capacity Calculation

Details: Accurate capacity calculation is crucial for proper pump selection, system design, and ensuring the pump meets the required performance specifications for various applications.

4. Using the Calculator

Tips: Enter flow rate in gpm and head in ft. Both values must be positive numbers to calculate valid capacity results.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for capacity calculation?
A: Capacity is calculated in units that represent gpm × ft, which indicates the pump's work output capability.

Q2: How does head affect pump capacity?
A: Higher head requirements typically reduce the flow rate, and therefore affect the overall capacity of the pump.

Q3: What is considered a good capacity value?
A: Capacity requirements vary by application. Higher capacity values indicate pumps capable of moving more fluid against greater resistance.

Q4: Can this calculator be used for all pump types?
A: This specific formula is designed for submersible pumps. Other pump types may have different capacity calculation methods.

Q5: How often should pump capacity be calculated?
A: Capacity should be calculated during pump selection, system design, and whenever changes are made to the pumping system.
