Different elements of a surface texture Surface is the area where this portion of work area is divided by a boundary line when the work done by other surface area. Normal surface: it is the theoretical, imaginary perfect surface obtained by calculating the mean of peak and valleys on the surface. Actual surface: the surface …
Bukingham-π(pi) Theorem This Bukingham-π(pi) theorem is used to determined the relation by discribing the physical phenomenon to the number of independent dimensions groups. The non dimension group is given by that a large number of physical variable are involved, in a dimensionally homogeneous containing ‘m’ fundamental dimensions. It is given by (n-m). The equation is …
Fin Effectiveness: 1. The thermal conductivity of materials for a given fin dimensions is determined by it. 2. The rate of heat transfer can be calculated from the surface with and without using fins, by using fin effectiveness relationship. 3. It is also used to determine the fin performance. Fin efficiency: 1. It is important …
Thermal conductivity of solids, gases and liquids Solids: Due to transfer of free electrons and lattice vibration heat conduction occurs. In some metals like pure type the heat conduction is more effectively due to moving of free electrons in single direction. Heat energy is transfer from high temperature to low …

COMPONENTS REQUIRED FOR VANE TYPE COMPRESSOR: The different type of parts are used to run the compressor is: 1.Suction pipe 2.Sliding vanes 3.Rotors 4.Casing 5.Valve 6.Roller bearings 7.Discharge pipe The vanes are generally made …
Vapour Compression System The main components of the vapour compression system is compressor, condenser, expansion valve, and evaporator.
PRE-WHIRL pre-whirl is known as the air to rotate and used to minimize the velocity before entering in to the impeller blade, it does not effect the mass of air flow and velocity of flow for reducing the reduce shock waves.due to running of centrifugal compressor with a high speed in gas turbine and jet …
Fuels Used in IC Engines A fuel is used to liberates enormous amount of heat by combustion.the fuel used in IC engine should have some properties. Because the properties of fuel affects the performance, durability and design etc. Properties of fuel used in IC Engines . High calorific value . Anti-knocking quality . Stability at …
