- A turbine is rated at 600hp when the flow of water through it is 82cu.m/sec. Assuming an efficiency of 92%, what is the head acting on the turbine?Design head at China’s Three Gorges Dam, the largest hydropower project in the world, is 80.6 m, and rated power output of each of the 32 turbine generator units is 700 MW. If the efficiency of each of the turbine generator units at full power output is 93.2%, what is the design flow through each turbine?The flow rate of the hydroelectric power plant in the figure is 50 m3/s, and 2 meters of water column energy loss occurs due to friction in the pipeline. Find the power that water transfers to the turbine. Calculate the theoretical and actual power of the turbine by taking the efficiency of the turbine-generator group, η = 0.92. (Answer: Ntheoric=52 MW and Nreal=48 MW)

If the efficiency of the turbine is 90%, how much power will be generated by the turbine?Pls answer ASAP. A hydroelectric power plant takes in 1060 ft³/s of water through its turbine and discharges it to the atmosphere at 7 ft/s. The head loss in the penstock is 66 ft. Estimate the power extracted by the turbine in horsepower. Show fbd.A hydroelectric power station is supplied from a reservoir having an area of 50 km2and a head of 50 m.If overall efficiency of the plant is 60%, find the rate at which the water level will fall when the stationis generating 30,000 kW
- The flow of a river is 150 cubic feet per second at a site where a 75 feet hydrostatic head canbe created by the erection of a dam. What is the potential capacity (in kW) of a hydroelectricpower plant if installed at this site? Consider that hydraulic efficiency of energy conversioncan be 80%, and that the electric efficiency can be 90%.The water behind a Dam is 206 m higher than the River below it. The water inthe dam is allowed to flow into the river to generate power.(i) Describe the energy conversions that take place at the hydro powergeneration plant.(ii) Apply the steady flow energy equation to determine the rate the water mustpass through the hydraulic turbines of this dam to produce 50 MW of power if theturbines are 100 percent efficient?A new hydraulic turbine is to be designed to be similar to an existing turbine with following parameters at its best efficiency point: DA = 3 m, n.A = 90 rpm, V.A = 200 m3/s, HA = 55 m, bhpA = 100 MW.

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%.Civil eng Need to solve this fluid question Q- A hydroelectric dam is being planned with a Francis turbine. The engineers choose to geometrically build up an already constructed hydroturbine with a stellar performance track record rather than starting from scratch. The current turbine (turbine A) is 2.05 metres in diameter and rotates at 120 revolutions per minute (omega_A = 12.57 rad/s). Dot V_A = 350m 3 / s, H_A = 75 of water, and bhpa = 242 MW are its optimal efficiency values. Turbine B, the new turbine, intended for a bigger facility. Its net head will be higher (H_B = 104r), but its generator will continue to spin at the same rate (120 rpm). Calculate the new turbine's diameter to ensure the most efficient operation, as well as the tilde V_R horsepower and turbine, B.Also Calculate and contrast the tiny (A) and large (B) turbines' turbine specific speeds.What is the cost to pump 1000 liters of water to the top of a 30 m high water tank?
