ENGINEERINGFor each case, determine the specified property value and locate the state sketches of the $p-v$ and $T-v$ diagrams.

ENGINEERINGWater from a stationary nozzle impinges on a moving vane with turning angle $\theta=120^{\circ}$. The vane moves away from the nozzle with constant speed, U=10 m/s, and receives a jet that leaves the nozzle with speed V=30 m/s. The nozzle has an exit area of 0.004 $\mathrm{m}^{2}$. Find the force that must be applied to maintain the vane speed constant. The wheeled cart shown rolls with negligible resistance. The cart is to accelerate to the right. The jet speed is V=40 m/s. The jet area remains constant at A=25 $\mathrm{mm}^{2}$. Neglect viscous forces between the water and vane. When the cart attains speed U=15 m/s, calculate the stagnation pressure of the water leaving the nozzle with respect to a fixed observer, the stagnation pressure of the water jet leaving the nozzle with respect to an observer on the vane, the absolute velocity of the jet leaving the vane with respect to a fixed observer, and the stagnation pressure of the jet leaving the vane with respect to a fixed observer. How would viscous forces affect the latter stagnation pressure, i.e., would viscous forces increase, decrease, or leave unchanged this stagnation pressure? Justify your answer.
