If a cooling tower supplies 80 ft of head pressure, what is the equivalent pressure at the pump suction?

To determine the equivalent pressure at the pump suction when given a head pressure in feet, you can use the conversion factor that 1 foot of head is approximately equal to 0.433 psi. Therefore, to convert the head pressure of 80 feet into psi, you multiply by this conversion factor:

80 ft x 0.433 psi/ft = 34.64 psi

Rounding to one decimal place offers an equivalent pressure of approximately 34.6 psi at the pump suction.

This calculation illustrates the relationship between head pressure in feet and pressure in psi, which is critical when evaluating the performance of a cooling tower and ensuring that sufficient pressure is maintained at the pump suction for optimal operation. Understanding this conversion is essential for engineers working with fluid systems to ensure pumps operate under the proper conditions.
