- The nozzle has a diameter of 40 mm. If it discharges water uniformly with a downward velocity of 20 m/s against the fixed blade, determine the vertical force exerted by the water on the bladearrow_forwardA 75 mm-diameter jet has a velocity of 33.5 m/s. It strikes a blade moving in the same direction at 21.3 m/s. The deflection angle is 150°. Assuming no friction, determine the final absolute velocity V2 of the water leaving the blade.arrow_forwardA uniform tube is used to siphon water from the large tank. If the pressure on the outside of the tube (the atmospheric pressure) is more than 20 kPa greater than the pressure within the tube, the tube will collapse. By using Bernoulli's equation, determine the minimum value of h allowed without the siphon collapsing. The density of water is 1000 kg/m3. Hint: Since the tube is uniform the flow speed in it is constant. The exiting flow from the tube is treated as free jet. 2 m V SARA 1 4 marrow_forward
- 8.) The pump shown draws water from reservoir A at elevation 10 m and lifts it to reservoir B at elevation 60 m. The loss of head from A to 1 is two times the velocity head in the 200 mm diameter pipe and the loss of head from 2 to B is ten times the velocity head in the 150 mm diameter pipe. Determine the rated horsepower of the pump and the pressure heads at 1 and 2 in meters when the discharge is 0.03 m3/sec.
