Homogeneous and Heterogeneous Nucleation
Homogeneous and Heterogeneous Nucleation: Homogeneous: In this nucleation process, the nuclei process takes place at pure liquid metal and this grows up to solidification completes.
Direct Solidification
Direct solidification: It is known that the process occurs in a particular direction. In this to supply the liquid metal throughout freezing the feeder heads are used to design to solidify after a long time.
About the Master Alloy and Characteristics of Master Alloy
Master Alloy: The master alloy purpose is mainly to obtain certain chemical reaction or to get a chemical composition by adding the alloy or some of the mixtures of elements to a metal bath is known as the master alloy. This is also known as an alloy in which one or more elements added in …

Difference between the pure metal and alloy?
The Difference between Pure Metal and Alloy is explained as follows: Pure metal: This metal has single phase materials that can form readily to a metallic bond which is done by composing of elements. Eg: Aluminium, copper etc… Due to the poor mechanical and physical properties, they are rarely used for engineering applications. These metals …
Vapour Compression System and its Working
Vapour Compression system: Vapour Compression System consist of Compressor, Condenser, Receiver, Expansion valve and Evaporator. In this type of system it consist of four processes. Compression process [1-2] Condensation process [2-3] Expansion Process [3-4] Evaporation process [4-1]
Define the first law of thermodynamics and explain about why it is the law of conservation of energy?
First Law of Thermodynamics In this, it states that both heat and work are mutually convertible. this is also said to be that when the heat is supplied to a system should equal to network done by it. When there is both heat and work is transferred then the net energy stored in the system …
Explain Internal energy, heat, and work
Internal Energy: The energy which is from the molecular arrangement and the motion of molecules, by this the energy is possessed in the boundaries of the system. This is also a type of stored energy. This type of energy does not depend on pressure and volume and it is a function of temperature. When the …
Thermodynamic Equilibrium and the conditions required to establish it?
Thermodynamic Equilibrium: It is said to be thermodynamic Equilibrium when the microscopic properties of the system unchanged and then it is isolated from the surroundings. by the Isolated system in the course of time and which does not gets depart from it, the state of thermodynamic equilibrium is formed. On the process of this stage, …

Macroscopic view and microscopic view
Explain about the Macroscopic view and microscopic view Macroscopic view: In this system the analysis is done by measuring properties like pressure, Temperature etc.. It does not explain about the mater of structure By the help of gauges, the properties are measured. In this system behave of all the molecules are equal. It takes less …
Components of the Vane type Compressor
Components that required to run the vane compressor are as follows: 1) Inlet pipe. 2) Sliding vane 3) Rotor 4) Casing 5) valve 6) Roller bearings 7) Outlet pipe Inlet Pipe: This inlet pipe is used to flow the fluid into rotor inlet and this made …
