A turbine system is harnessing the energy of flowing water from reservoir 1 to reservoir 2. The difference in elevation between the two reservoirs is 120ft. For a design flowrate of 50ft^3/s, the head loss is 30ft. Solve the efficiency of the turbine if the actual energy extracted is 100hp. Neglect the difference in atmospheric pressure between the reservoirs. O 24.90% O 35.60% O 40.80% O 19.60%
