A pressure gauge reads 350 psi. If it was pumping water, what would the ft of head be?

To convert pressure in psi (pounds per square inch) to feet of head for water, you can use the formula that relates pressure to head, which is derived from the hydrostatic pressure equation. Specifically, the relationship considers the density of water and the acceleration due to gravity.

The conversion factor is approximately 1 psi equals 2.31 feet of head for water. To find the height of the water column in feet that corresponds to a pressure of 350 psi, you multiply the pressure by this conversion factor:

350 psi × 2.31 feet/psi ≈ 808.5 feet.

Rounding the calculation gives you approximately 808 feet.

This makes the conversion and understanding of the fluid's behavior under pressure essential for millwrights, especially when dealing with systems that move fluids. This process allows for estimates and efficient system designs. Therefore, the correct conversion reflects the altitude at which the water would exert the same pressure, demonstrating the practical application of conversion in fluid dynamics.
