A pump steadily delivers water through a hose terminated

by a nozzle. The exit of the nozzle has a diameter of 0.6 cm

and is located 10 m above the pump inlet pipe, which has a

diameter of 1.2 cm. The pressure is equal to 1 bar at both the

inlet and the exit, and the temperature is constant at 20° C. The

magnitude of the power input required by the pump is 1.5 kW,

and the acceleration of gravity is g = 9.81 m/s^2. Determine

the mass flow rate delivered by the pump, in kg/s.

2. Relevant equations

Not sure. I think

m_dot (deltaPE) = W

I don't know if I can use the work by the pump though.

m_dot = rho*Volumetric flow rate

3. The attempt at a solution

Well these are the only equations I can think of and I'm not sure if these are right. Any help where to go form here would be appreciated.
