Manufacturer's data for a submersible utility pump are

The owner's manual also states, These ratings are based on discharge into 25 -mm-diameter pipe with friction loss neglected. Using 20-mm-diameter garden hose adaptor, performance will be reduced approximately 15 percent." Plot a performance curve for the pump. Develop a curve-fit equation for the performance curve; show the curve-fit on the plot. Calculate and plot the pump delivery versus discharge height through a \(15-\mathrm{m}\) length of smooth \(20-\mathrm{mm}-\) diameter garden hose. Compare with the curve for delivery into 25-mm-diameter pipe.
