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.

Characteristics of Entrepreneur/ Traits of an entrepreneur

  Characteristics of Entrepreneur/ Traits of an entrepreneur  1. Creativity.  2. Professionalism.  3. Risk-taking.   4. Passion.   5. Planning  6. Knowledge.   7. Social Skills.  8. Open-mindedness towards learning, people, and even failure.  9. Empathy   10. Customer is Everything    1. Creativity:                     Entrepreneurs usually have the knack to pin down a lot of ideas and act on them. Not necessarily every idea might be a hit. But the experience obtained is gold. Creativity helps in coming up with new solutions for the problems at hand and allows one to think of solutions that are out of the box. It also gives an entrepreneur the ability to devise new products for similar markets to the ones he’s currently playing in.    2) Professionalism:                                 Professionalism is a quality which all good entrepreneurs must possess. An entrepreneurs mannerisms and behavior with their employees and clientele goes a long way in and discipline. Self-di

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 combination and L is the center distance between two rollers. Then,           Sin θ =  (h / L).                θ = sin^-1 (h / L).             θ = Slope of object su

Different types of business structures, Business Ideas and their implementation:- • Discovering ideas and visualizing the business • Activity map • Business Plan

Different types of business structures:- 1. Sole Proprietorship:-                            A sole proprietorship is the simplest and most common form of business structure. In this type, the business is owned and operated by a single individual. The owner has complete control over the business and assumes all liability for its debts and obligations.  Some key features of a sol e proprietorship include:   • Ownership: The business is owned by one person, known as the sole proprietor.  • Liability: The sole proprietor has unlimited personal liability for the business's debts and obligations. This means that personal assets can be used to satisfy business liabilities.  • Decision- Making: The sole proprietor makes all the decisions regarding the business's operations.  • Taxes: The owner reports business income and expenses on their personal tax return.  2. Partnership:-                    A partnership involves an agreement between two or more individuals to sha
