When the pump shown in Fig. P5.121 is stopped, there is no flow through the system and the spring force is zero. With the pump running, a 6 -in.-diameter jet leaves the pipe, and the spring force is \(420 \mathrm{lb}\). The water surface elevation in the tank is constant. Determine the water flow rate and the power consumed by the pump. Assume quasi-steady flow.
