$(15$ pts$)$ For this problem, refer to the figure associated with problem $4\mathrm{.}8.$ from Hydraulic Lessons. The figure is included below for your convenience. works best, you need to answer each of the following questions and then decide which pump is the best.

For Pump $2824$A:

A$.$ What is the operating point for this system and pump curve scenario? Provide the flowrate $($gpm$)$ and the pump head $($ft$)$

B$.$ What is the pump efficiency $(\%)$ at the operating point?

C$.$ What is the NPSHr $($ ft $)$ from the pump chart given the operating point?

D$.$ What is the best efficiency point $($BEP$)$ for this pump? Provide just the flowrate $($gpm$)$ corresponding to the point where the pump efficiency is at its maximum.
