Fig shows a schematic diagram layout of nuclear power plant. In nuclear power plants, the reactor function is similar to the furnace of steam power plant. It contains pressure vessel, fuel rods, moderator, shielding as shown in fig. There are various types of reactors used in practice which will be discussed later. The fuel elements

Micro-hydro, defined as a plant between 10kW and 200kW, is perhaps the most mature of the modern small-scale decentralised energy supply technologies used in developing countries. Micro hydro power plant is energy from water sources such as the ocean, rivers and waterfalls. “Micro-hydro” means which can apply to sites ranging from a tiny scheme to

A method of maintaining the speed of the turbine is constant irrespective of variation of the load on the turbine known as governing of turbine. The governors regulate the rate of flow to the turbine in such a way that the speed of the turbine is maintained constant as far as possible under varying load

Rotational speed of the turbine Specific speed Maximum efficiency Part load efficiency Head Type of water Runaway speed Cavitation Number of turbine units Overall cost. Rotational speed of the turbine Turbines are used to produce mechanical energy which is again converted into electrical energy by coupling the generator through the shaft. Here, the speed of

The pelton wheel is a tangential flow impulse turbine and now in common use. Leston A Pelton, an American engineer during 1880, developed this turbine. Fig shows the schematic arrangement of a pelton wheel. Pelton wheel consists of the following main parts. Penstock Spear and nozzle Runner with buckets Brake nozzle Outer casing Governing mechanism

Water is the cheapest source of power. A hydro-electric power plant is aimed at harnessing from water flowing under pressure. In hydroelectric power plants, the energy of water are utilized to drive the turbine hydro or waterpower is important only next to the thermal power. Hydroelectric power was initiated in India in 1897 near Darjeeling.

In cooling towers, the warm water is discharged from the condenser and fed the cooled water back to the condenser. The rate of evaporation of water in cooling tower and subsequent reduction in water temperature depend upon the following parameters. The exposive time. Amount of water surface exposed. Relative humidity of air. Velocity of air

In the file related examples so far we have not concerned ourselves with error situations. In particular, we have assumed that the error handling in file we opened for reading already existed, and that those opened for writing could be created or appended to. We’ve also assumed that there were no failures during reading or

Most programs need to save data to disk file I/O and read it back in. Working with disk file I/O requires another set of classes: ifstream for input, fstream for both input and output, and of stream for output. Objects of these classes can be associated with disk files, and we can use their member

In the STATIC example in before chapter, “Objects and Classes,” we introduced static data members. As you may recall, a static data member is not duplicated for each object; rather a single data item is shared by all objects of a class. The STATIC example showed a class that kept track of how many objects
