The ${\mathrm{NPSH}}_{\mathrm{R}}$ for a pump is given by the manufacturer as $6.0\mathrm{m}$. This pump is being used to pump water from a reservoir at a rate of $0.25{\mathrm{m}}^3/\mathrm{s}$ through a pipe of diameter $25\mathbf{cm}$. The water level in the reservoir is $1.0$ $\mathbf{m}$ below the pump. Atmospheric pressure is $101.3$ $\mathbf{KN}/{\mathbf{m}}^2$ and water temperature is $20^{?}\mathbf{C}$. Assume total head loss in the suction pipe is $1.2\mathbf{m}$ of water. Calculate the ${\mathbf{NPSH}}_{\mathbf{A}}$ in (m) and determine whether or not the pump is safe from cavitation effects.
