Question
Transcribed Image Text:1. The performance data of a water pump follow the curve fit Havailable =Ho +aV, where the pump's shutoff
head Ho="K", coefficient a="Y" m/(Lpm)?, the units of pump head H are meters, and the units of Vare liters
per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at
a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system
curve simplifies to Hrequired =(Z2-Z1)+bV², where elevation difference z2-z1="X" m, and coefficient b = "L"
m(Lpm)?. Calculate the operating point of the pump (a) V. operating and (b) Hoperating) in appropriate units
(Lpm and meters, respectively). Read the equation carefully.
