It is simplest sense hydraulics has to do with certain characteristics of liquids such as water and oil. People query   so far as the automotive chassis is concerned is related to the effects of pressure applied to a liquid. It is called Hydraulic pressure. Hydraulic pressure used in the b raking system in shock absorbers and in power steering systems. It is also used in automotive transmission system such as control circuits, fluid coupling, and torque converter, in engine it is more used in water pump, oil pump, hydraulic valve filters, fuel pump and others.  It has been seen that increasing the pressure on a gas will compress the gas into a smaller volume. When pressure increase in a liquid its volume do not reduce. Its volume stay at the same even through the pressure on it is greatly increased. It is incompressible because a liquid can not be compressed into a smaller volume. The molecules of the liquid are rather close together as opposed to a gas in which

In a real impactor , the nozzle flow impacts on a flat plate placed at right angle to the nozzle flow and flows  radially outwards on the plate. Hence, the flow field is constant in real impactor provided the flow rate Q 1   through the nozzle is constant, whereas in a virtual impactor this is not the case. Here keeping the total flow  rate Q 1 through nozzle constant, the minor flow rate Q m   through collection prove can be changed by  changing the major flow rate Q 2 through the vacuum pump. Hence, in virtual impactor , the effective velocity responsible for pushing the particles into the minor flow is a  difference of velocities (V 1 -V 2 )   , Where   V 1    and V 2     are the velocities corresponding to the nozzle flow  rate and major flow rate. The experimental analysis has been done in set II   in accordance with the methodology described below. Stokes number for a virtual impactir is given by: Stk=   Ʈ (V 1 -V 2 )    

Changing the size of narrowly distributed aerosols: The size of narrowly distributed aerosols generated in the aerosols generator can be  controlled by controlling solution concentration (C c ) . , Minor flow rate (Q m )   and total flow rate (Q 1 ) .  Effect of change in solution concentration: The size of aerosols with narrow size distribution can be varied by changing the concentration  of liquid solution according to the relation. C c = V p /V d = d p 3 /d d 3 Where       C c = Solution concentration    V p = Volume of solute from which final particles are formed, V d = Volume of solvent  d p = Diameter of particle and d d = Diameter of droplet We know d d   because it is the cut off diameter of droplets in the virtual impactor . Forconstant  flow rate through the virtual impactor, the cut off diameter , d d , in the virtual impactor is  always constant. Hnece, depending on the final particles diameters , d

The increase of pressure on a gas decrease of its volume.    This also increases its temperature. In naturally temperature or heat is nothing or nor less than speed of molecular motion. The object or substance is hot when the molecules   move   fast. The object is cold when molecules move slowly. In a piece of ice molecules are motion slowly they all more or less hang together. When the ice remains is solid. If the ice is heated it melts. Then molecules begin to move faster and they can no longer hang together to from a solid. And the ice convert to water. When the water is heated its boiled   and create vapor where all molecules move so faster and jump clear to liquid. When a cubic volume pressure increase that’s time heat increase. It has been seen that gaseous molecules are move so fast than other molecules.
