Water is to be supplied at a rate of 5000 kg/s to a hydro-electric generator located at the bottom of a lake at a height h. If the efficiency of the turbine-generator is 75% and of the generator 95%; using the first law of thermodynamics calculate the following: the efficiency of the turbine, the height in meters needed to produce 2413.8 hp of electric power, and the shaft power supplied by the turbine to the generator in KW.
a smoke stream from a smoke generating tube is often used as a simple method of flow visualization in wind tunnels.
A steam power plant for an automotive vehicle is proposed as shown. The boiler has a volume of 50 litres and initially contains 90% liquid and 10% vapor by volume at 100kPa. The burner is now turned on and when the pressure in the boiler reaches 700k..
