The rise and fall of a liquid surface in a small thin tube, when it is immersed vertically in a liquid is called capillarity (capillary action). The rise of the liquid surface in the tube is called as capillary rise and the fall of the liquid surface is called as capillary depression. The capillary rise […]

What is a Supercharger? It is used to pressurize the air at intake or increase the air density supplied to an internal combustion engine, more air means more oxygen allowing it to burn more fuel and to get more power by increasing in air during the combustion inside an engine. Here we will learn about

For the air intake in the engine, there are two procedures, one is a natural aspiration and another is a forced aspiration. Naturally aspirated engines take the air from the outside environment through the intake manifold from the air filter. This kind of engine was used in earlier days but nowadays almost every engine is

What is Anti-lock Braking System? Anti-lock Braking System also known as anti-skid braking system (ABS) is an automobile safety system that prevents the locking of wheels during braking and avoids uncontrolled skidding. The modern ABS system allows steering during braking which gives more control over the vehicle in case of sudden braking. The main advantages
Surface Tension (ST) is defined as the tensile force acting on the free surface of liquid which is in contact with a gas or on the surface in between two immiscible liquids such that the contact surface behaves like a thin membrane under tension. It is more interesting to know how this tensile force acts

Engineering mechanics is the branch of applied science which works with the laws and principle of mechanics. Whatever the body we seen around us experiences forces and due the forces experienced by the body they undergo motion. The study of object which is either in motion or at rest because of the forces acting on

Cavitation is a phenomenon of formation of vapor bubbles of a flowing liquid in a region where the pressure of the liquid becomes equal or less than the vapor pressure. When these vapor bubbles reaches into the region of higher pressure, they collapse and creates high impact pressure. These high impact pressure created by the

Centrifugal pump is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. The flow of liquid takes place in radial outward direction which is reverse of the inward radial flow reaction turbine. It is used in different areas where fluid is

Centrifugal Clutch is a type of clutch in which centrifugal force is used to connect the engine drive shaft with the shaft of the transmission. It is placed in between the engine flywheel and the transmission system. Its main function is to connect the engine shaft with the transmission shaft. It works more efficiently at

Fluid coupling is also known as hydraulic coupling. It is a hydrodynamic device that is used to transfer rotational power from one shaft to another by the use of transmission fluid. It is used in the automotive transmission system, marine propulsion system, and in industries for power transmission. It is used as an alternative to
