Water from a stationary nozzle impinges on a moving vane with turning angle θ = 120. 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 m 2. Find the force that must be applied to maintain the vane speed constant.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
