Take the density of water to be 1000 kg/m3 and the momentum-flux correction factor to be 1.03 at both the inlet and the outlet. Water m kg/s 50 cm Determine the anchoring force needed to hold the elbow in place. The anchoring force needed to hold the elbow in place is The resultant direction of the force is 155 ⁰. 429 N.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
In a horizontal pipe water flows at a rate of 9.1 L/s. Here, the pipe has two sections, one with a diameter of 10.16 cm and the other with a diameter of 5.08 cm, with a gradual smooth reducing section. In this case, a mercury manometer is used to measure the pressure difference. If friction is negligible how would I find the differential height of mercury between the two sections? If the manometer on the 5.08cm pipe section was replaced with a pitot tube how would the reading change? any help would be deeply appreciated
