The **theoretical atmospheric** **pressure at sea level** (14.7 psi) will support a column of water 34 feet high:

14.7 psi x 2.31 ft/psi = 33.957 ft, or 34 ft

At an elevation of 1 mile above sea level, where the atmospheric pressure is 12 psi, the column of water would be only 28 feet high: 12 psi x 2.31 ft/psi [....]

**BASIC PUMPING CALCULATIONS **

Certain computations used for determining various pumping parameters are important to the water/wastewater operator. In this section, we use basic-pumping calculations relevant to the subject matter.

PUMPING RATES

Important Point:

$The rate of flow produced by a pump is expressed as the volume of water pumped

during a given period.The mathematical problems most often encountered by water/wastewater [....]
