$4\mathrm{.}66$ Figure P$4\mathrm{.}66$ provides steady$-$state operating data for a

pump drawing water from a reservoir and delivering it at a

pressure of $3$ bar to a storage tank perched above the

reservoir. The mass flow rate of the water is $1\mathrm{.}5k\frac{g}{s}.$ The

water temperature remains nearly constant at $15C,$ there is

no significant change in kinetic energy from inlet to exit, and

heat transfer between the pump and its surroundings is

negligible. Determine the power required by the pump, in

kW $.$ Let $g=9\mathrm{.}81\frac{m}{s^2}.$
