$5\mathrm{.}6\mathrm{.}1.$ The following table provides the results of a pump performance test.

$\backslash$table$[[$Discharge $($gpm$){?}^a,0,200,400,600,800,1,000],[$Dynamic head $($ft$),150,145,135,120,90,50]]$

${?}^{aA}$ common flow unit for pumps is gallons per minute $($gpm$).$

$($a$)$ Plot the pump characteristic $($performance$)$ curve.

$($b$)$ Plot the characteristic curve for two pumps in series.

$($c$)$ Plot the characteristic curve for two pumps in parallel.

$($d$)$ What pump configuration would work for a required flow of $1,700gpm,$ which must overcome a head of $80ft?$

$($e$)$ What pump configuration would work for a required flow of $1,700gpm,$ which must overcome a head of $160ft?$
