The discharge pressure gauge on a pump reads 23 psi. What is the discharge pressure in feet?

To convert pressure from psi to feet of head (a common measurement in hydraulic systems), you can use the conversion factor that 1 psi is approximately equal to 2.31 feet of water height. This conversion applies because it is based on the weight of water and the pressure exerted by a column of water.

In this case, with a discharge pressure reading of 23 psi, you multiply that value by the conversion factor:

23 psi × 2.31 ft/psi = 53.13 ft

Rounding this to a more standard figure, it is approximately 53 ft. Therefore, the correct answer reflects the accurate conversion of the pressure reading into feet of water, making the discharge pressure 53 feet. This understanding is critical in wastewater treatment operations for determining how well a pump is performing and ensuring adequate pressure is maintained throughout the system.
