1. The problem statement, all variables and given/known data 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.
