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-

Read the question carefully and give me right solution with clear calculations.
Note: If you don't know the solution please leave it but don't give me wrong solution.
At a river a suitable site for a run-of-the river installation has an available head of 13 m between the water intake and the turbine house. Environmental guidelines permit to extract water for hydropower only if it is in excess of 2.8 m3/s. Estimate the power generated in kW when the flow in the river is 10.9 m3/s for a turbine with an efficiency of 90%. Present the answer as integer in kW.

- There is a big old pipe that runs from Lake Whatcom that was used to supply water to the now defunct Georgia Pacific mill. Let’s see if the city could make a microhydropower plant work using that infrastructure. The pond at Lake Whatcom is 100 meters above sea level. Where Whatcom creek crosses Woburn the elevation is 20 meters above sea level and that’s where the turbine would be. The flow fluctuates but averages 3 cubic meters per second. With a turbine that is 80% efficient, how much power can we obtain from this stream in MW under average flow conditions?arrow_forwardCooling 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.arrow_forwardThe water taken from a stream at an average speed of 5 m/s is transferred to the turbine by a forced (pressurized) pipe system in order to generate electrical energy. After passing through a 10 m3/s flow rate turbine passing through a pressure pipe, it is poured into the lake downstream. the total irreversible (irreversible) load (energy) loss Dec the piping system between points 1 and 2 (excluding the turbine) is determined as 8 m. Calculate the theoretical and actual power of the turbine by taking the efficiency of the turbine generator set, η = 0.85.arrow_forward
