A hydroelectric power plant has a turbine whose speed must be fixed at 240 rpm. The turbine is impulse type with 12 m diameter. When the flow rate at the nozzle of the penstock is 10 m3/s, the generated electricity is 60 MW. Compute the velocity of the water jet (i.e., Find Vi).
You are designing a hydroelectric plant. The turbine has an efficiency of 88% and the generator has an efficiency of 92%. You design the water flow rate to be 110 m3/s. The water elevation drop is 120 m. Disregarding frictional loss in the piping, what do you expect the electric power output to be in MW?
3. In a small hydroelectric power station, the turbine uses the energy of the water in the reservoir behind the dam to produce 12000 horsepower. The circular channels before and after the turbine have a diameter of 90 inches. If the head loss across the dam can be calculated from hloss=cV²/2g where c=8 and V is the water velocity in the circular channel, calculate the volumetric flow rate, Q, through the system and the corresponding head loss for h=400 ft...
ENGR 320 Exam2 Name 1: (15+5 pts) A hydroelectric power plant takes in 25 m's of water through its turbine and discharges it to the atmosphere at V2-I m/s. The head loss in the turbine and penstock system is 10 m. Assuming turbulent flow, a -1.12, (a) What it the power in MW extracted by the turbine? () If the efficiency of the turbine and electrical generator is 85% what is the net power (in MW) generated by this plant?...
A micro hydro turbine is used to generate hydroelectric power by letting liquid water from a high elevation run through the turbine to a low elevation. The turbine is under a steady state operation condition. The inlet water and outlet water are at elevations of 10 m and 2 m, respectively. The inlet and outlet diameters are 0.3 m and 0.5 m, respectively. The inlet pressure is 2.5 bar and the outlet pressure 1 bar. The inlet and outlet temperatures...
3. For the following system determine the power that can be extracted by the turbine for a volumetric flow rate of 0.007 [m3/s. Include appropriate minor losses (elbows & entrance). - Cast iron, L88, d 7 [c 45 [m H20 Turbine
A turboprop engine consists of a diffuser, compressor, combustor, turbine, and nozzle. The turbine drives a propeller as well as the compressor. Air enters the diffuser with a volumetric flow rate of 63.7 m3/s at 40 kPa, 240 K, and a velocity of 180 m/s, and decelerates essentially to zero velocity. The compressor pressure ratio is 9 and the compressor has an isentropic efficiency of 85%. The turbine inlet temperature is 1240 K, and its isentropic efficiency is 85%. The...
A power generation system with a turbine and a generator is located at a dam, where the water falls from 106.074 m height to the turbine. Assuming turbines having 100% efficiency, what should be the flow rate of water (in kg/s) to produce 7.486 MW of power? (Take gravitational acceleration as 9.81 m/s2.
