A 90° elbow as shown in Figure Q2b is used to direct water flow at a rate of 30 kg/s in a horizontal pipe upward. The diameter of the pipe is 10 cm and the elbow discharges water into the atmosphere and thus the pressure at the exit is the local atmospheric pressure. The elevation difference between the centers of the exit and the inlet of the elbow is 35 cm. The weight of the elbow and the water is assumed to be negligible. i. Apply a proper form of energy conservation principle, determine the anchoring force needed to hold the pipe bend in place. ii. Then, recommend a suitable angle in between 20° to 120° from the flow direction to reduce the anchoring force. Justify your recommendation. Figure Q2b 35 cm Water 30 kg/s Figure Q2b

An open container made of metal is placed ona scale. Water flows into the container through an opening at the top. At the same time, water flows from the container through the two-equal 45° deflection opening at the sides (Figure Q2). The metal cylinder height is 65 cm, having a diameter of 26 cm, and weighs 21 N when empty. Under normal steady flow conditions, the water level maintained at 58 cm measured from the bottom of the container. One of your friends claims that we can treat this as a simple statics problem by saying that the scale will measure the weight of the volume of water in the tank plus the tank weight only but you disagree with his/her statement. You make a message that says that flow analysis is required. Proof that you are right.|
In unloading a grain from a hold of a ship, an elevator lifts the grain through a distance of 12 m. Grain is discharged at the top of the elevator at a rate of 2.0 kg each second, and the discharged speed of each grain particle is 3 m/s Find the minimum-horsepower motor that can elevate the grain in this way if it is 60% efficient.
Water from a large reservoir drives a turbine, and exits as a free jet from a pipe of diameter D. The jet is deflected by a vane, and the horizontal force required to hold the vane is F directed to the left. Given: h = 40m, D = 0.15m, 0 = 30°, F, = 1500N, and Pw = 1000 kg/m³.

A reciprocating compressor draws in 500 gal per minute of air whose density is 0.079 lbm/cu ft and discharges it with density of 0.304 lbm/cu ft. At the suction, p1 = 15 psia; at discharge, p2 = 80 psia. The increase in the specific internal energy is 33.8 Btu/lbm and the heat transferred from the air by cooling is 20 Btu/lbm.

In Figure 1, a reducing elbow is used to deflect water flow at a rate of 18 kg/s in a horizontal pipe upward 40o while accelerating. The elbow discharge water into the atmosphere. The cross sectional area of the elbow is 120 cm2 at the inlet and 10 cm2 at the outlet. The elevation difference between the centers of the outlet and the inlet is 50 cm.

In the jet impact experiment, water jet impacts on a curved vane in the vertical direction. As shown in the figure below, the exit has an angle with respect to the vertical direction. The distance from the nozzle to the vane surface at the exit is h. The water volume flow rate is measured to be Q, the density of water is p, and the cross section area of the nozzle is A₁. Assume that the flow has reached the steady state. (1) Use the Bernoulli's equation to determine the velocity Vout at the exit of the vane. Assume that friction between water and the curved vane can be neglected.
