Presentation on “Thermodynamic system”

contents:-

• Definition• Types & their examples -open system -closed system -isolated system

Thermodynamic System:-

• A definite quantity of matter on which we focus our attention for its thermodynamic analysis i.e., to study the change in properties due to exchange of energy in the form of heat annd work is called thermodynamic system

• The system may be a quantity of steam, a mixture of gas and vapour or a piston cylinder assembly of an internal combustion engine.

-• System:-Anything which are kept in

consideration is called System.• Surrounding:-Everything external to the system

is known as Surrounding.• Boundary:-The thermodynamic system and

surroundings are separated by an envelope called Boundary of a system.

• Universe:-Thermodynamic system+surrounding=Universe

Classification of Thermodynamic system

• Open system:-in open system, the mass as well as energy transfer may take place between system and its surroundings.

• Most of Engineering devices are open system.

Example of open system:-

• Internal combustion engines• Air compressor• Water pump• Steam engine• Boiler• Tutbine

Closed system:-*In closed system, the mass with in the boundary of the system remains constant and only the energy transfer may take place between the system and its surroundings.

Examples of closed system

1.Pressure cooker2.A rubber balloon filled with air and tightly closed3.The gas confined between a piston and cylinder

Isolated system:-

*In an isolated system,neither mass nor energy transfer takes place between the system and its surroundings.

Examples of isolated system

1.Thermos flask2.The universe
