Section 5: Irrigation and Drainage Engineering
Irrigation Pumps
Subtopic: Irrigation Pumps
Question Statement:
An irrigation pump operates at atmospheric pressure head $H_{atm} = 10.3\text{ m}$, suction lift $h_s = 3.5\text{ m}$, suction pipe friction loss $h_{fs} = 0.8\text{ m}$, and water vapor pressure head $H_v = 0.5\text{ m}$. Net Positive Suction Head Available is $NPSHA = H_{atm} - h_s - h_{fs} - H_v = 10.3 - 3.5 - 0.8 - 0.5$. The $NPSHA$ in meters is:
