A reducing elbow in a horizontal pipe is used to deflect water flow by an angle = 45° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The cross-sectional area of the elbow is 150 cm² at the inlet and 25 cm² at the exit. The elevation difference between the centers of the exit and the inlet is 40 cm. The mass of the elbow and the water in it is 56 kg. Determine the anchoring force needed to hold the elbow in place. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet. The density of water is 1000 kg/m3, and the flow rate of water is 30 kg/s.

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.

Water is stored in a pressurised container at a height HT= 8.4 m. It then moves through a horizontal pipe which has a height HP= 0.2 m off the ground. A fault occurs, and the water in the pipe is ejected vertically out of a valve, as shown in the figure. The jet reaches a maximum height Hj off the ground. The density of water is ρ=1000 kg/m^3, and the gauge pressure in the tank is pT= 45 kPa.a) Find the maximum height of the jet, Hj (in metres)b) Find the velocity at which the jet leaves the pipe (in m/s)
