What is Pressure to Head Calculator?

A Pressure to Head Calculator is a tool used to calculate the head or height of a fluid column in a closed or open system based on the pressure and specific gravity of the fluid. The calculator is commonly used in hydraulic engineering, water supply systems, and fluid dynamics. This article will provide an overview of the calculator, the formula, and how to use it.

Formula

The formula used by the Pressure to Head Calculator is:

h = p / 0.433 * SG

where:

  • h = Head or height of the fluid column (ft)
  • p = Pressure of the fluid (PSI)
  • SG = Specific Gravity of the fluid

The constant value of 0.433 is the conversion factor from PSI to feet of water. This formula assumes that the fluid is incompressible and the pressure is measured in PSI absolute.

Example

Suppose the pressure of a fluid is 60 PSI, and the specific gravity is 0.9. To calculate the head or height of the fluid column, we can use the Pressure to Head Calculator and the formula provided:

h = 60 / 0.433 * 0.9

h = 155.97 ft

Therefore, the height of the fluid column is 155.97 ft.

How to Calculate

To use the Pressure to Head Calculator, follow these steps:

  1. Input the pressure in PSI in the “Pressure” field.
  2. Input the specific gravity of the fluid in the “Specific Gravity” field.
  3. Click the “Calculate” button.
  4. The head or height of the fluid column in feet will be displayed in the “Head” field.

FAQs

What is specific gravity?

Specific gravity is the ratio of the density of a substance to the density of water at a specified temperature. It is a unitless quantity.

Can the Pressure to Head Calculator be used for compressible fluids?

No, the Pressure to Head Calculator assumes that the fluid is incompressible. If the fluid is compressible, other factors such as temperature and volume must be considered.

What is the unit of measurement for the pressure and head values in the calculator?

The Pressure to Head Calculator uses PSI for pressure and feet for head or height of the fluid column.
