Quiz 3 (solved)Water (density=1,000 kg/m3) flows through a 90° elbow at a rate of 40 kg/s (Figure d). The diameter of the entire elbow is 15 cm. The inlet gage pressure is 2,605 Pa and the outlet gage pressure is 1,605 Pa. Neglecting weight of the elbow and water and taking the correction factor as 1, determine the z component of the force (Fz ).,A pump with a useful pumping power of 3 kW is used to pump water (density=1,000 kg/m3) from a lake to a nearby large pool (Figure b). The free surface of the pool is 35 m above the surface of the lake. If the total head loss of the system is 8 m, determine the flow rate of water in m3/h. (g=9.81 m/s2),A water jet strikes a rectangular block through a cavity (open to atmosphere), as shown in Figure c and deflected back at an angle of 45° from the horizontal. Mass flow rate of the water is 18 kg/s and the average velocity of the water is 35 m/s. Assuming same area of water at the inlet and outlet and if the block does not move, determine the axial (horizontal) friction force between the block and the floor (Fx ). Neglect gravitational forces.,In which of the following cases, volumetric flow rate in is equal to the volumetric flow rate out through a cylindrical pipe?,Which one of the following is the simplified energy equation between points 2 and 3 for Figure a? (rho=density),
