Water Pressure Formula:
From: | To: |
Definition: This calculator converts water column height in feet to pressure in pounds per square inch (psi).
Purpose: It helps engineers, plumbers, and technicians determine water pressure based on elevation differences in water systems.
The calculator uses the formula:
Where:
Explanation: The formula converts the weight of a column of water into pressure at its base.
Details: Accurate pressure calculations are essential for designing water systems, ensuring proper pump selection, and maintaining system safety.
Tips: Simply enter the height of the water column in feet. The value must be > 0.
Q1: Why is the conversion factor 0.433?
A: This represents the pressure exerted by 1 foot of water (0.433 psi/ft) at standard conditions.
Q2: Does this work for any liquid?
A: No, this is specific to water. Other liquids would require different conversion factors based on their density.
Q3: How accurate is this calculation?
A: It's accurate for pure water at standard temperature (4°C/39.2°F). Temperature variations can cause slight deviations.
Q4: What's the pressure at 100 feet of water?
A: Approximately 43.3 psi (100 × 0.433).
Q5: How does this relate to head pressure in pumps?
A: Pump head is often measured in feet of water - this calculation converts it to psi for system design.
