Pump Flow Rate Formula:
| From: | To: |
The fountain pump flow rate determines how much water the pump can circulate per hour. Proper pump sizing is essential for achieving the desired water display effect and ensuring efficient operation of your fountain system.
The calculator uses the simple formula:
Where:
Explanation: This formula provides a basic estimate of the required pump flow rate based on the vertical height the water needs to be pumped.
Details: Correct pump sizing ensures optimal fountain performance, prevents pump overload, reduces energy consumption, and extends equipment lifespan. An undersized pump won't achieve the desired water effect, while an oversized pump wastes energy and may cause splashing.
Tips: Enter the fountain height in feet. The height should be measured from the water surface to the highest point where water will be discharged. Always round up to the nearest available pump size for safety margin.
Q1: Why multiply height by 100?
A: This is a standard rule of thumb in fountain design - for every foot of height, you need approximately 100 gallons per hour flow rate to achieve a good water display.
Q2: What if my fountain has multiple tiers?
A: Use the height to the highest tier. For complex multi-tier fountains, consider consulting with a fountain specialist for precise calculations.
Q3: Are there other factors to consider?
A: Yes, also consider pipe diameter, number of nozzles, desired water effect, and head loss due to pipe fittings and bends.
Q4: What's the typical range for residential fountain pumps?
A: Residential fountain pumps typically range from 100 to 3000 gallons per hour, depending on fountain size and design.
Q5: Should I add a safety margin?
A: Yes, it's recommended to add 10-20% to the calculated flow rate to account for friction losses and ensure adequate performance.
