In a hydroelectric project, a discharge of 400 m/s is available with net head of 32 m. If two turbines of same size having specific speed Ns are required to give an efficiency of 90 % then Ng (in Sl unit) of each turbine is_ (Assume speed of each turbine to be 152 r.p.m.).

Question 4: The three gorges dam is rated at maximum output. If its generating efficiency is 90 % and its head is 81 m what is the rate of flow in (kg/s) of water through its turbines at maximum output.

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?

Pls answer thank you! At a proposed hydroelectric plant site, the average elevation of headwater is 600 m, the tailwater elevation is 480 m. The average annual water flow is determined to be equal to the volume flowing through a rectangular channel 4 m wide and 0.5 m deep and average velocity of 5.5 m/sec. Assuming that the plant site can develop if the hydraulic turbine that will be used has an efficiency of 80% and generator efficiency of 92%. Consider a headwork loss of 4% of the available head. Find the annual energy produce in kW.
