I need only the h pump equation to plot the performance.

The centrifugal pumps whose performance

curves for water are given in figure $1$a$)$ and $1$b$)$

will be used in the water system of the figure $2.$

The friction factor and the pipe diameter are

$0\mathrm{.}010$ and $150$ mm throughout,

respectively. Minor losses are negligible.

a$)$ What water flow rate, in gallons per minute,

will result in pump $1$a and $1$b$?$

b$)$ What is the pump head $1$ a and $1$ b $?$

c$)$ What is the efficiency $1$ a and $1$ b $?$

d$)$ Determine the head loss for $1$ a and $1$ b
