It is basically a physical science, based on the observations of physical phenomena followed by the experimental evidence which verify that it is correct. Finally, once the principles have been accepted then these observations are translated into mathematical
There is a variety of compressors to choose from for refrigeration services. The most common are centrifugal, reciprocating, and screw compressors. The type of refrigerant used also influences the compressor choice.
Refractory is defined as the quality of a material to retain its strength at higher temperature. These materials are used inside the furnaces, kilns incinerators and reactors.
Furnace is a device use for heating or It is equipment to heat material to change their shape like rolling and forging or to change the properties of the material. Most of the time furnace is used for melting metals for casting.
For separating gaseous and liquid mixtures, the fluid is brought into contact with some small porous solid. When the bed is completely saturated it is taken out for regeneration and sometimes a new bed is placed.
A Thermodynamic system can easily be defined as a quantity of matter or a region in the universe selected for study. The mass or region outside the system is defined as surrounding. The region or the space that keeps the system a part of its surrounding is called
Thermodynamic studies the system with equilibrium stage Equilibrium means that the system is balance i.e no unbalance force is within the system. An equilibrium system does not undergo any change since it is isolated from its surroundings.
Property is defined as the characteristic of any system. Some known properties are pressure (P), Temperature (T) , Volume (V) and mass(M). Some properties of system which are less familiar are Viscosity, Modulus of elasticity, thermal conductivity, electric resistivity, thermal expansion coefficient
Internal Energy is stated as the summation of all microscopic forms of energy. It is defined as the sum of kinetic and potential energy of the molecule since it is related to the molecular structure and molecular activity.
Scientists began to research thermodynamics in the nineteenth century in order to describe the operation of steam engine and to find its maximum accomplishment. The engines were created by Thomas Savery in 1697 in England and Thomas Newcomen in 1712. These engines opened a new window of Engineering
