In this article we will discuss about the methods of compounding and governing of steam turbines. Compounding of Steam Turbine: The steam turbines operate at very high speed in the range 30000 r.p.m. The devices as a load operate at slow speeds in range of 1000 to 4000 r.p.m. It becomes necessary to reduce the speed of steam turbine using [...]

Lubrication Systems and Methods of Lubrication used in IC Engine! Introduction to Lubrication in I.C. Engine: The machine parts which have relative motion rub against each other. The rubbing surfaces are never perfectly smooth, even when they are highly polished. If they are observed under a microscope, small depressions and elevations can be seen. These depressions and elevations get interlocked [...]
In this article we will discuss about the Otto Cycle and Diesel Cycle of IC engine. The question arises of these engines, which are most efficient and what are the factors that impose limitation on the maximum efficiency. Sadi Carnot was the first scientist to study this problem and he found that the maximum possible efficiency of an engine, working [...]
