Precipitation: This includes all the water that falls from atmosphere to the earth surface. It is mainly of two types: Liquid precipitation (Rainfall) Solid precipitation (Snow, Hail). Run-off: It is that portion of precipitation which makes its way towards streams, lakes or oceans. Run-off can be possible only when the rate of precipitation exceeds the

a) Stator frame: The stator frame is built of welded steel structure. The frame is provided with feet to rest on sole plates. b) Stator core: The stator core consists of segmental, varnish insulated stampings of cold-rolled silicon alloy steel. Ventilation ducts are provided at intervals along the stator core. c) Stator windings: It is

We know that before feeding water to boiler water should be purified and softened. This increases the efficiency of boiler and makes longer life. In thermal power plants, source of water comes from lake or river. Water is pumped from the river or lake. Pumped water comes with a lot of impurities and dissolved gases. Hence water treatment plant is maintained

India’s Rajasthan is going to generate maximum solar power by 2022 as per NASDAQ report. It is learnt that, in Rajasthan availibility of solar radiation is more and lot of space easily available to install number of solar panels. National Solar Mission, an ambitious plan by the Indian government to install 20 million solar lights and 20 million square

As we know that power output depends on the KVA and cosΦ. A consumer has to pay the electricity charges for his maximum KVA plus on the basis of units consumed. If a consumer improves the power factor, then there is reduction in his maximum KVA demand and consequently there saving during maximum demand of

This article has been published as per observing practically in G-40 BHEL Electronic governor for Kaplan Turbine. In modern hydraulic power plants turbines are directly coupled to electric generators. Any variations in the load, the generator has to maintain its speed which is fixed by the number of pair and required frequency. When there is

This type of reactors can utilize high coolant temperatures without applying high pressures and at the same time can have high rate of heat transfer between coolant and water in the heat exchanger. As we know that metals are good conductor of electricity when they are in liquid state. Even metals attains higher temperatures at moderate pressures. Normally this type of reactor are

Cooling water is tapped from the penstocks and connected to a common in let header through a duplex strainer with isolating valves on either side. The inlet header is connected to an out let header through many numbers of cooling water pumps and a non-return valve. Isolating valves are provided on either side of the

This article has been published as per observing practically in G-40 BHEL Electronic Governor for Kaplan Turbine. The normal functioning of governor and servomotors is dependent upon a reliable source of oil under pressure. This pressure is maintained constant within the desired limits. The system consists of a pressure pumping set and pressure receiver. The

Natural Uranium contains only small quantity of fissionable U-235. Fissile isotopes like U-238 and PU-239 are converted into fissionable U-235 within reactor, very rapidly. The reactor breeds to produce fissionable U-235. Hence it is called Fast breeder reactor. Here vessel in which the necessary quantity of enriched uranium or plutonium is kept without moderator. The
