Water Pressure Formula:
| From: | To: |
Water pressure calculation determines the pressure exerted by a column of water based on its height. This is important in various engineering and plumbing applications to ensure proper water flow and system design.
The calculator uses the water pressure formula:
Where:
Explanation: The formula calculates the pressure at the bottom of a water column based on its height, with 0.433 psi representing the pressure exerted by one foot of water.
Details: Accurate water pressure calculation is essential for designing plumbing systems, irrigation systems, water towers, and various hydraulic applications to ensure proper water flow and system performance.
Tips: Enter the height of the water column in feet. The value must be valid (height > 0). The calculator will compute the water pressure in psi.
Q1: Why is the conversion factor 0.433?
A: This factor comes from the density of water and unit conversions. It represents the pressure in psi exerted by a 1-foot column of water.
Q2: Does this formula work for other liquids?
A: No, this specific formula is for water. Other liquids would require different conversion factors based on their specific gravity.
Q3: What are typical water pressure values in residential systems?
A: Most residential water systems operate between 40-80 psi, with 50-60 psi being ideal for most applications.
Q4: How does elevation affect water pressure?
A: Water pressure decreases with elevation due to reduced height of the water column. Each foot of elevation change affects pressure by approximately 0.433 psi.
Q5: Can this calculator be used for water tower design?
A: Yes, this calculation is fundamental for determining the required height of water towers to achieve desired pressure in distribution systems.
