Fluid Machines

 EXCHANGE OF ENERGY:

A machine wherein rotary motion is obtained by centrifugal forces which result from a change in the direction of high velocity fluid jet that issues from a nozzle. A hydraulic turbine uses the potential and kinetic energy of water and convert it into usable mechanical energy. The fluid energy is available in the natural or artificial high level water reservoirs which are created by constructing dams at appropriate places in the flow path of rivers. 



When water from the reservoir is taken to the turbine, transfer of energy takes place in the blade passages of the unit. The mechanical energy made available at the turbine shaft is used to run an electric generator which is directly coupled to the turbine shaft. 

The power generated by utilizing the potential and kinetic energy of water has the advantages of:

Despite the heavy capital cost involved in constructing dams and reservoirs, in running pipelines and in turbine installation (when compared to an equivalent thermal power plant) different countries have tried to tap all their water power resources. Appropriate types of water turbines have been installed for most efficient utilization.

Heat Engine

Heat Engine : (Power Plant of an Automobile)  A device which is used to convert one form of energy into mechanical energy is called an Engine . The heat energy produced by burning of the fuel is converted into mechanical power, then it is called a Heat Engine.  Heat engines are classified into two types.  1.External Combustion Engine  2.Internal Combustion Engine  1. External Combustion Engine  An external combustion engine is a Heat engine where a working fluid, is heated by combustion in an external source like Boiler. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. The combustion process takes place outside the mechanical engine system.   Eg. Steam Engines, Ancient Marine Engines  2.Internal Combustion Engine  An internal combustion engine (ICE) is a Heat engine where the combustion of a fuel and air occurs inside the engine combustion chamber that is an integral part of an engine....

Fluid Mechanics

Differential Manometer 1.Introduction Differential manometers are used to measure the difference of pressures between two points in a pipe or in two different pipes. There are two types of differential manometers.             1.   U-tube upright differential manometer             2.   U-tube inverted differential manometer 1.2  U-tube Upright Differential Manometer It is used to measure pressure difference at two points in a pipe or between two pipes at different levels. Case 1 - U-tube upright differential manometer connected at two points in a pipe at same level The construction and arrangement of a manometer connected at two different points, A and B, of a pipe is shown in figure 1                              Fig.1U-tube upright differential manometer    Let,          ρ 1  = densit...
