A riser gains 75 feet of elevation. Using 0.433 psi per foot, approximately what static pressure reduction results?

A25.0 psi
32.5 psi
C43.3 psi
D28.9 psi

Why B is correct

Multiply the elevation change by the supplied factor: 75 ft × 0.433 psi/ft = 32.475 psi, or approximately 32.5 psi. This is elevation loss only, before friction and device losses.
