THERMODYNAMICS,THERMODYNAMICS SYSTEM,TYPES OF THERMODYNAMIC SYSTEM,PROPERTIES OF SYSTEM,AND ITS TYPES

THERMODYNAMICS:-It is the branch of engineering in which we study about the conversion of heat energy into mechanical energy.

THERMODYNAMICS SYSTEM:-It is the region or area around the space where all the thermodynamics process takes place or thermodynamics analyis is done.

**SURROUNDING:-Every thing apart from the system is called surrounding.

*BOUNDARY:-It is an imaginary or real surface which separate system and surrounding.

*TYPES OF THERMODYNAMIC SYSTEM

There are three types of thermodynamics system.

1. Open system:- A system in which mass as well as energy can transfer from system to surrounding or surrounding to system is known as open system.

2. CLOSED SYSTEM:- A system in which mass remain constant but energy can transfer from system to surrounding or vice-versa.

3. ISOLATED SYSTEM:- A system in which neither mass nor energy can transfer from system to surrounding or vice-versa.

**PROPERTIES OF SYSTEM **

Every system has certain characteristics by which its physical condition may be described.

eg:- volume, pressure, temperature,etc.

such characteristics are called propertics of system.

THERE ARE TWO TYPES OF PROPERTIES OF SYSTEM

1. Extensive property:-Those thermodynamic properties which depends upon the mass or number of substance and size of the system are called extensive peoperty.

eg:-mass,volume,all types of energy,enthalpy,entopy, internal energy.

2. INTENSIVE PROPERTY:-Those thermodynamic properties which are independent of mass and size of the system are called intensive property.

eg:- temperature, pressure,density,viscosity,specific heat capacity etc.

NOTE:- RATIO OF TWO EXTENSIVE PROPERTY ALWAYS GIVE INTENSIVE PROPERTY.

Compressor,and its types:-Hermetically Sealed Compressors and Semi-Hermetically Sealed Compressors.

Compressors are mechanical devices that are used to increase the pressure of a gas or vapor by reducing its volume. There are various types of compressors available in the market, each with its own unique features and advantages. Two of the most commonly used compressors are Hermetically sealed and Semihermetically sealed compressors. Hermetically Sealed Compressors:- A hermetically sealed compressor is a type of compressor that is completely sealed and is designed for small applications like refrigeration and air conditioning units. The hermetic compressor is called so because its motor and compressor are placed in a single sealed casing. The casing is welded or brazed shut, which prevents any gas or liquid from leaking in or out of the compressor. The hermetically sealed compressor is also known as a ‘sealed c...

Subject:-Measurement & Metrology, Angle measuring instruments:-Sine bar , Clinometer , Bevel Protector.

Angle measuring instrument:- → The instrument which is used for measurement the slope of any object surface is called angle measuring instrument . →T here are 3 types of angle measuring instrument. ( I)Sine bar ( II)Clinometer ( III)Bevel Protector SINE BAR:- → sine bar is an angle-measuring instrument that measures slope of any object with the help of slip gases and a dial indicator. → it is a steel piece mounted over two hardened steel cylindrical roller having equal diameter. → To make it lighter in weight small holes are drilled along steel piece. Principle:- →The working of sine bar is based on the princiople of trigonometry. In this one roller is placed over combination of slip gauges and another is placed over table surfaces. →If H is the height of slip gauge c...

Disaster Management:- Disaster, Effects of Disaster, Hazard, Vulnerability and types of vulnerability.

Disaster:- A Disaster refers to a sudden or extreme event that causes significant damage, destruction, or disruption, resulting in human, economic, and environmental losses that exceed the ability of the affected community or society to cope using its own resources. Disasters can be natural(such as earthquakes, floods, hurricanes)or human-made(such as industrial accidents, terrorist attacks). → A disaster can be defined as an event that occurs in most cases suddenly and unexpectedly, causing severe disturbances to people, or objects affected by it, and resulting in loss of life and harm to the health of the population, the destruction or loss of community property and severe damage to the environment. → A disaster is a natural or manmade event that negatively affects life, property, livelihood, or industry often resulting in permanent changes to human societies, ecosystems, and th...
