8. For the moving cart and vane in the figure below, let the jet be water of 3 in diameter at 35 ft/s. If the vane angle is 0= 60 and the cart is moving at 15 ft/s, compute the required Fx. P, Vj, Aj F Fuel mf 9. The rocket in the figure below has a supersonic exhaust, and the exit pressure pe is not necessarily equal to pa. Determine the force F required to hold this rocket on the test stand. mo Oxidizer D = 3 in 5 ft Pa Vc Pump h? Fx D = 6 in = constant 10. A jet airplane moving at 900 km/hr takes 700 N/s of air into is engine, burns 15 N/s of fuel, and discharges the exhaust gasses at atmospheric pressure. If the thrust of the engine is 40,000 N, what is the absolute velocity of the gases in meters per seconds? F y 11. Gasoline (SG = 0.68) flows through the pump in the figure below at 3 ft/s. Head losses between (1) and (2) are 10 ft, and the pump delvers 30 hp to the flow. What should the mercury manometer reading h be in feet? #Pe Pe, Ae, Ve Mercury V
