potential pressure differences and any friction losses The term Head is used to express the different parts of the power or energy requirements The head is a measure of how high the fluid can be reached and is usually expressed in length units m ft which The pump head is generally divided into three parts 1

Calculation of Transient Piping Loads Caused by Pressure Flow

Since the pipe is horizontal the difference in pressure across the pipe segment is accounted for entirely by friction The pressure drop is only 2 9 psi so the frictional force is obviously small For instance the force on each end is P A = 68 8 psi 672 in 2 = 46 2 kips whereas the frictional force is P 2 P 1 A = 2 9 psi 672 in 2
