In the realm of fluid dynamics and engineering, understanding the relationship between different units of pressure is crucial. One such relationship is between feet of head (a unit measuring the height of a liquid column) and pounds per square inch (psi), a standard unit of pressure. The Feet of Head to psi Calculator is a specialized tool designed to convert the pressure value from feet of head to psi effortlessly. This conversion is essential for engineers, technicians, and professionals involved in water supply, heating, and cooling systems, where accurate pressure measurements are pivotal for system design and maintenance.
Formula of Feet of Head to psi Calculator
The formula for converting feet of head to psi is straightforward and rooted in the principles of fluid mechanics. It is expressed as:
psi = feet_of_head / 2.31
Where:
psiis the pressure in pounds per square inch.feet_of_headis the height in feet.
This formula is derived from the physical principle that a 1-foot column of water exerts a certain amount of pressure at its base, which can be converted into psi, a more universally recognized pressure unit.
General Terms Table
To aid in understanding and applying this conversion without the need for calculations each time, the following table provides some common conversions based on the formula provided:
| Feet of Head | Pressure in psi |
|---|---|
| 1 | 0.43 |
| 5 | 2.16 |
| 10 | 4.33 |
| 15 | 6.49 |
| 20 | 8.66 |
| 25 | 10.82 |
| 30 | 12.99 |
| 50 | 21.65 |
| 100 | 43.29 |
This table serves as a quick reference to estimate the pressure in psi for a given height in feet of head, facilitating easier decision-making and planning in various applications.
Example of Feet of Head to psi Calculator
To illustrate the application of the formula, consider a scenario where you need to determine the pressure in psi at the base of a water tower that has a height of 50 feet. Using the formula:
psi = 50 / 2.31 = 21.65
Thus, the pressure exerted at the base of the water tower is approximately 21.65 psi.
Most Common FAQs
