QUESTION 2 a) Draw the velocity triangles at the inlet and outlet sections of a centrifugal pump whose impeller curvature is in the clockwise direction and the impeller is rotating in the counterclockwise direction. Assume no swirl flow at the inlet.

5. A sprinkler rotates around fixed Point C. The nozzle on Arm A has broken off. So, water exits Arm A in the radial direction, relative to the sprinkler at 2 m/s and the radial velocity of the water is increasing at 0.5 m/s². The sprinkler arms are rotating around Point Cat = 6 rad/s, and because the nozzle has broken, it is decelerating with Ö= -1 rad/s². At that moment, what are the radial (vr) and theta (ve) components of velocity of the water exiting the sprinkler at Point A? b. Express the velocity vector in rectangular coordinates, in terms of i and j unit vectors. a. Y X view from the top 0.1 m 8 = 6 rad /s Ö= -1 rad/s² A *w = 2 m/s *w = 0.5 m/s²

Draw a velocity triangle as shown in the figure in question. The velocity triangle immediately after the impeller exit is also required.

Please solve question four

Note: The following is part of a multi part question where you are asked to calculate the velocity at station 2, Pressure at station 2, and force exerted by the fluid on the bend in the x-direction. Please complete all the above steps and select the correct answers as the relevant questions arise in the quiz. Water flows through the 180 degree bend and Nozzle assembly as shown in the Figure below. Assume the assembly lies in the horizontal plane such that gravity is irrelevant (There is no height difference between Station 1 and Station 2) Calculate the velocity of the fluid at the nozzle exit (Station 2) Hint: Use MASS CONSERVATION...REMEMBER THERE IS NO HEIGHT DIFFERENCE 160 mm V2 Section (2) 300 mm V1 Section (1) P1 = 100 kPa %3D V1 = 2 m/s %3D Select one:

Problem 5 A Pelton turbine has six nozzles (see the figure to the right, credit Wikipedia). Each of the nozzles has an outlet velocity of 100 m/s and an exit area of 0.05 m². If the radius of the turbine is 3 meters, and the rotational velocity is 20 rad/s, what is the power generated by the turbine?

A Francis radial-flow hydroturbine has the following dimensions, where location 2 is the inlet and location 1 is the outlet: r2 = 2.00 m, r1 = 1.30 m, b2 = 0.85 m, and b1 = 2.10 m. The runner blade angles are ?2 = 71.4° and ?1 = 15.3° at the turbine inlet and outlet, respectively. The runner rotates at n. = 160 rpm. The volume flow rate at design conditions is 80.0 m3/s. Irreversible losses are neglected in this preliminary analysis. Calculate the angle ?2 through which the wicket gates should turn the flow, where ?2 is measured from the radial direction at the runner inlet. Calculate the swirl angle ?1, where ?1 is measured from the radial direction at the runner outlet. Does this turbine have forward or reverse swirl? Predict the power output (MW) and required net head (m).

Find the offset angle for an axial pump that delivers 50 gpm at 1750 rpm. The volumetric efficiency is 95%. The pump has a nine 0.75 inch diameter pistons arranged on a 6-in piston circle diameter.
