Pump Flow Rate Formula:
| From: | To: |
The Water Feature Pump Size Calculator helps determine the appropriate pump flow rate for waterfalls based on the width of the water feature. Proper pump sizing ensures optimal water flow and aesthetic appeal.
The calculator uses the pump flow rate formula:
Where:
Explanation: This formula provides a general guideline for selecting pump sizes based on waterfall width, ensuring adequate water flow for visual effect.
Details: Correct pump sizing is essential for efficient water feature operation. An undersized pump may result in inadequate water flow, while an oversized pump can waste energy and cause excessive splashing.
Tips: Enter the width of your waterfall in inches. The calculator will determine the recommended pump flow rate in gallons per hour (GPH).
Q1: Why is width used to determine pump size?
A: Width determines the distribution of water flow across the waterfall. Wider features require higher flow rates to maintain consistent water coverage.
Q2: What if my waterfall has multiple tiers?
A: For multi-tier waterfalls, calculate based on the widest section or consider increasing the flow rate by 10-20% for additional height.
Q3: Are there other factors to consider?
A: Yes, factors like vertical height (head pressure), pipe diameter, and desired water effect (gentle flow vs. strong cascade) should also be considered.
Q4: What is the 50 multiplier based on?
A: The multiplier of 50 GPH per inch is a general industry standard that provides good water coverage for most residential waterfall applications.
Q5: Should I round up or down when selecting a pump?
A: It's generally recommended to round up to the nearest available pump size to ensure adequate flow, especially if you want a more dramatic water effect.
