FLUID MECHANICS: THE ENERGY EQUATION:

The attached image shows a common consumer product called a water pik. The device uses a motor to drive a piston pump that produces a jet of water (d = 3mm, T = 10oC) with a speed of 25m/s. Estimate the minimum electrical power in Watts that is required by this device. Hints: (a) Assume the power is only used to produce kinetic energy of the water in the jet. (b) In the time interval delta t, the amount of mass that flows out of the nozzle is delta m, and the corresponding amount of kinetic energy is (delta m V2/2)
