Marks: +1, -0

A centrifugal pump has the following specifications 0.15 m diameter, 100 m long pipe with velocity of water 2.26 m/s. and friction coefficient 0.015. what is the frictional head loss?

10.4
12.6
15.1
13.8

Solution:

d = 0.15 m, l = 100 m, v = 2.26 m/s, f = 0.015.

{h}_{{f}}={4 {flv}^{2}}/{2 {gd}}

{h}_{{f}}={4 \×0.015 \×100 \×2.26^{2}}/{2 \×9.8 \×0.15}

{h}_{{f}}=10.41
