= 15 6.8 An engineer, who is designing a water toy, is making prelimi- nary calculations. A user of the product will apply a force F₁ that moves a piston (D = 80 mm) at a speed of Vpiston = 300 mm/s. Water at 20°C jets out of a converging nozzle of diameter d mm. To hold the toy stationary, the user applies a force F2 to the handle. Which force (F₁ versus F2) is larger? Explain your answer using concepts of the momentum principle. Then calculate F₁ and F2. Neglect friction between the piston and the walls. Vpiston F2 PROBLEM 6.8 d -Jet
