A 100-ft3/s water jet is moving in the positive x-direction at 18 ft/s. The stream hits a stationary splitter, such that half of the flow is diverted upward at 45° and the other half is directed downward, and both streams have a final average speed of 18 ft/s. Disregarding gravitational effects, determine the x- and z-components of the force required to hold the splitter in place against the water force.
A water jet with volume flow rate of 3 m³/s is moving in the positive x-
direction at a speed of 6 m/s. The stream hits a stationary splitter, such
that half of the flow is diverted upward at 45º and the other half is
directed downward at 45°, and both streams have a final average speed of
6 m/s. The gravitational effects and friction loss are considered to be
negligible. Determine the x- and z-components of the force required to hold
the splitter in place against the water force. Note that the pressure of the
water jet at inlet and outlet sections is the atmospheric pressure and the
density of water is taken as 1000 kg/m³.

- In typical jet-engine testings, a static thrust stand similar to the one shown below is used to mount the engine. In engine testing, pressure is usually expressed in gauge pressure. At the engine inlet, air is steadily introduced, and its cross-sectional area is 1.2 m². The inlet condition is given by 250 m/s, 50 kPa (gauge) and -50°C. The nozzle-exhaust gas has a velocity of 550 m/s, and its absolute pressure is 101 kPa, the same as the atmospheric pressure. (a) Estimate the thrust force applied to the stand during the engine testing. Assume that the incoming air has the same mass flow rate as the exhaust gas. (b) Repeat (a) when fuel supplied to the engine is taken into account. The fuel mass flow rate into the engine is equal to 2% of the mass flow rate of incoming air.
