Cooling water for a chemical plant must be pumped from a river 2,500 ft from the plant site. A preliminary design calls for a flow rate of 600 gpm and a 6" steel pipe. Calculate the pressure drop and the annual pumping costs if power costs 3 cents per kilowatt hour. Would the use of an 8" steel pipe reduce the power cost enough to offset the increased pipe cost? Assume $15/ft for the installed cost of 6" pipe and $20/ft for the installed cost of 8" pipe. Annual charges are estimated at 20% of the installed cost.

1.) Compute the specific speed for a pump operating at 4000 rpm delivering 600 gal/minof water at a total head of 150 ft.
A pipe is used to deliver water at a rate of 3.8 m³/s from the intake to the turbine. The difference in elevation between the intake’s water surface and the turbine is 200 m. Knowing the headloss in the pipeline from the intake to the turbine is 8 m, find the power (in kW) generated by the turbine if its efficiency is 80%.

8. Energy Equation Water at the Lake William Dam enters a hydraulic turbine through a 30 cm diameter pipe at a rate of 0.6 m³/s and exits through a 25-cm diameter pipe. For the system, elevation effects are negligible and the pressure drop across the turbine is measured to be 148 kPa. For a combined turbine-generator efficiency of 83 percent, calculate (a) hurbine and (b) Wubrine- You look in the FE handbook and see: W turbine = 7/turbine-gen”ightutine, e turbine-genhtubine, e 30 cm diameter 25 cm diameter Turbine Generator

The dam on Hydaway Lake on Liberty Mountain (not really sure if a dam exists)has the potential to provide some power to the Hydaway Outdoor Center. Before that canhappen Sparky Consulting needs to determine the potential power output. A diagram of thedam and proposed turbine location are provided below. The lake water flows through an 8-inchdiameter pipe (location A) into the turbine. The discharge pipe downstream of the dam has avolumetric flow rate of 300 ft3/min. The head loss through the piping system is 5 ft. The specificgravity of the water is 62.4 lbf/ft3. What is the power output (in horsepower) of the turbine if theturbine efficiency is 70 percent?
Water at 60 F from a lake through 500 ft if 4in ID cast iron pipe at a water turbine 250 ft below the surface of the lake. After flowing from the turbine, the water is discharged into the atmosphere through a horizontal 50 ft section of the same pipe. The turbine power output is 10hp when the water in the discharged pipe is flowing at 5 ft/s. What is the turbine efficiency defined as the actual power output of the turbine divided by the power output that would be withdrawn if there are no friction within the turbine. If the turbine were by passed, what would be the flow rate of water through the 500 ft of 4in pipe. a. Draw the diagram. b. Solve the problem. Provide complete solution.
