Answer Question 6: the marked choice is the correct answer. 

5) Water is pumped from a lower reservoir to an upper reservoir using a pump with
a curve of hp = 400 - 4 Q2, where hp is in feet and Q is in cfs. With a static lift of
150 feet, the system delivers a discharge of 5.0 cfs. If the friction factor can be
considered to be a constant and the minor losses ignored, what will be the
operational discharge in cfs if the static lift is increased to 200 feet?
