Hf = 0.02 * (1000/0.1) * (1.5^2/2*9.81) = 2.29 m Hs = 20 - 10 = 10 m Hm = 10% of H = 0.1 * (2.29 + 10) = 1.23 m H = 2.29 + 10 + 1.23 = 13.52 m
H = Hf + Hs + Hm
Hf = f * (L/D) * (V^2/2g)
The margin of safety is added to account for any uncertainties in the system: booster pump head calculation xls
The static head is the difference in elevation between the suction and discharge points: Hf = 0
