How many feet of head does 1 pound per square inch (psi) of water produce?

The relationship between psi and feet of head in water is based on the weight of water and the acceleration due to gravity. Specifically, 1 psi corresponds to a column of water that is approximately 2.31 feet high.

This conversion is derived from the fact that water has a weight of about 62.4 pounds per cubic foot. To understand this conversion: for every 1 psi increase, you can determine the equivalent height of water by using the formula:

Head (feet) = (Pressure (psi) x 2.31) / specific weight of water (in psi).

Since 1 psi is effectively the weight of a column of water supported over an area of 1 square inch, it directly translates to a height of approximately 2.31 feet. This value is useful in various practical applications such as designing water supply systems or understanding pressure in fluid systems. Thus, the correct answer indicates the standard relationship between pressure and water head in the context of fluid mechanics.
