V. SUPPLY SYSTEM CONSIDERATIONS

B. Head

The English unit for measuring head is feet. The equation, expressing pressure (psi) in units of feet, is:

Head = psi x 2.31

S.G.

Where,

S.G. = Specific Gravity @ pumping temperature.

Example 8:

Find the head in units of feet (ft.) of crude oil, with a S.G. = 0.8 @ pumping temperature, at 20 psi pressure.

Head = 20 x 2.31 = 57.75 ft.

0.8

Example 9:

Find the head in units of feet (ft.) of mercury with a S.G. = 13.6 @ pumping temperature), at 20 psi pressure.

Head = 20 x 2.31 = 3.39 ft.

13.6
