Design & SizingPregunta 22 de 110
A booster pump adds 52 psi. What is the equivalent head, in feet, that the pump develops? Use 1 psi = 2.31 ft of head.
a.52 ft
b.120 ft
c.78 ft
d.231 ft
Explicación
Head = psi x 2.31 = 52 x 2.31 = 120 ft. The 2.31 factor is the reciprocal of the 0.433 psi-per-foot relationship and converts pressure to the equivalent vertical column of water. Pump curves are usually plotted in feet of head, so this conversion is needed to read them.
