PSI Formula:
| From: | To: |
The pump head to PSI conversion calculates pressure in pounds per square inch (PSI) from pump head measured in feet of water. This conversion is essential for understanding pump performance and system pressure requirements in hydraulic systems.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 2.31 comes from the relationship where 1 foot of water head equals approximately 0.433 PSI, and its reciprocal is 2.31.
Details: Converting pump head to PSI is crucial for system design, pump selection, pressure calculations, and ensuring proper operation of hydraulic systems. It helps engineers and technicians match pump capabilities with system requirements.
Tips: Enter the pump head in feet of water. The value must be positive and greater than zero. The calculator will automatically compute the corresponding pressure in PSI.
Q1: Why is the conversion factor 2.31?
A: The factor 2.31 comes from the density of water and gravitational acceleration. Specifically, 1 foot of water head equals 0.433 PSI, so dividing by 0.433 gives approximately 2.31.
Q2: Does this conversion work for fluids other than water?
A: No, this specific conversion factor applies only to water. For other fluids, you need to account for the specific gravity of the fluid.
Q3: What is pump head?
A: Pump head is the height to which a pump can raise water, representing the energy imparted to the fluid by the pump, measured in feet or meters.
Q4: How accurate is this conversion?
A: The conversion is highly accurate for water at standard conditions (4°C). Temperature variations can cause minor changes in water density, affecting accuracy slightly.
Q5: When is this conversion most commonly used?
A: This conversion is widely used in plumbing, irrigation systems, fire protection systems, HVAC systems, and industrial pumping applications where water is the working fluid.
