2 psi is equal to how many inches of water?

To determine how many inches of water are equivalent to 2 psi (pounds per square inch), we utilize the conversion factor between psi and inches of water column. Specifically, 1 psi is approximately equal to 27.7 inches of water.

Given this conversion factor, you can calculate the equivalent of 2 psi in inches of water by multiplying 2 psi by 27.7 inches of water per psi:

2 psi × 27.7 inches of water/psi = 55.4 inches of water.

This calculation shows that 2 psi converts directly to 55.4 inches of water, making it the correct answer. Understanding these conversions is vital for applications in fluid mechanics and pressure measurements within control systems, as they often utilize various units of pressure depending on the specific context or equipment being used.
