How can you increase the efficiency of a Pelton turbine?
To maximize efficiency, or jet must reach precisely the center of each bucket of Pelton. Thus, the jet gives the maximum pulse to each bucket, as indicated above no bucket design that the rotation of the turbine depends on the speed of the jet of water.
What is the efficiency of a steam turbine?
The practical thermal efficiency of the steam turbine varies depending on the size of the turbine, the loading conditions, the loss and the loss of friction.
How do you increase the volumetric efficiency of an engine?
The flatter, larger and larger valves help to reduce the restrictions and improve the volumetric efficiency. They also help to increase the elevation of the valves, by further reducing their restriction. The polishing of the intake removes part of its restriction, as well as the enlargement. The use of a high-speed air filter or none also improves the results.
How do you increase the output of a generator?
Figure 1 shows a single rotation coil, in a real generator there would be a lot of spins. You could increase the output voltage of a generator by turning it faster, increasing the number of spins in the coil or using stronger magnets, AC output.
Which turbine has maximum efficiency?
The large Francis turbines are designed individually for each location to operate with the highest water flow rate possible and the water head, usually for 90 years.
What is the significance of specific speed in turbine?
The specific speed is an index used to predict the desired performance of the pump or turbine. I mean, it provided the overall form of the turbine. It is the form of turbines that provided the characteristic flow and head so that the designer can select a pump or turbine more suitable for a certain application.
