Wells and Pumps

A centrifugal pump is installed at a location where atmospheric pressure head is $10.1\text{ m}$ and water vapor pressure head is $0.3\text{ m}$. The suction pipe head loss is $h_{fs} = 0.8\text{ m}$. If the pump requires a Net Positive Suction Head of $\text{NPSH}_R = 3.0\text{ m}$, calculate the maximum permissible suction lift height $h_s$ above the sump water surface in $\text{meters}$ to prevent cavitation.
