Water is pumped from a tank (elev. 110 m) to the top
of a hill (elev. 150 m) through 1,000 m of 500-mm diameter steel
pipe (ε = 0.0003 m). The pump motor is rated at 150 kW (i.e. brake
horsepower). Assume pump efficiency of 70%.
a) Develop an equation to determine discharge flow rate by trial
and error
b) Solve equation developed in part a)
c) Briefly explain why a centrifugal pump is appropriate for this
application.
If answer is wrong thumbs down ?
