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)

The pressure reading coming out of a pump is 150 lb. Every 50 ft section reduces the pressure by about ​4%. What will the nozzle pressure be at the end of six 50 ft​ sections? ​(​Hint: One reduction of ​24% is not equivalent to six reductions of ​4% each. You must do this the long​ way.)

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

Problem 3: Water issues from a hole in a large tank, as shown in the attached figure.Assuming frictionless flow, find L.

A centrifugal pump running at 1859 rpm has impeller dimensions of b₁ = 53, b₂ = 21, r₂ = 285, r₁ = 82, B₁ = 20°, B₂ = 10° (all dimensions in mm). Determine the theoretical head (meters) if water enters the blades radially. Round off your answers to 2 decimal places. (15 mins)

For the cart of figure, compute the force on the wheels caused by deflecting the jet and thecompression of the spring, if its stiffness is 1.6 kN/m.

Question 1: Water is expelled by a jet to the environment (i.e. the water flow is surrounded by atmospheric pressure). To change the direction of the water flow, this enters to a curved pipe as show in the figure (top view perspective). Calculate the forces exerted by the flow to the pipe in x and y direction (both horizontal). Use a water density of 1000 kg/m³, Q=1 m³/s, diameter d-0.3 m. Follow the 4 steps explained in the lectures and state your assumptions clearly. 30 Question 2: Repeat question 1 but change the curvature from 30 degrees to 90 degrees. How the forces change? 90

A water discharge of 10 m3/s is to flow through this horizontal pipe, which is 1 m in diameter. If the head loss is given as 7V2/2g (V is velocity in the pipe), how much power will have to be supplied to the flow…

Q6: The U-bend in the figure below is connected to a flow system by flexible hoses that transmit no force. The pipe has an ID of 3 in. Water is flowing through the pipe at a rate of 600 gal/min and density is 1000 kg/m³. The pressure at point 1 to 5 psig and at point 2 is 3 psig. What is the vertical component of the force in the support? Neglect the weight of the pipe and fluid. Flow FIGURE Vertical pipe U-bend. Flex hoses Support

Calculate the force exerted by a stationary curved vane that deflects a 2 inch diameter stream of water through a 120 degree angle. The volume flow rate is 175 gal/min. The stream is directed parallel to the positive x horizontal. 120° (Work on Paper Required)
