Pitot tube is a mechanical device which is used to measure velocity of flow at any point in a pipe or a channel. It was invented by French engineer Henri Pitot and modified by French scientist Henry Darcy. Pitot Tube works on a basic principal of fluid Mechanics and that is, if a fluid stops… Read More »
Set screw (also known as Grub screw) is a special type of screw which is used to prevent relative moment of two parts. Unlike screw, a set screw is threaded over its entire length. In many applications, a setscrew is used instead of key to prevent relative motion between the hub and the shaft. The… Read More »
Nuts are internally threaded fasteners. They have internal tapping. They are generally meant to be used with bolts. Together nut and bolt is used to assemble mechanical parts. Bolt is a male part and nut is a female part. Nuts are generally made of metals. Types of nuts There are basically two types of nuts… Read More »
A bolt is a type of threaded fastener (like a screw) and is a male part. It is generally made of a metal. It is used to keep two or more hardware parts together (in a specific position). Shank of the bolt is only partially threaded, just to accommodate a nut. A bolt is sometimes… Read More »
Screws are fasteners with helical grooves on their shank. These grooves can be either throughout the shank or only in the beginning. These grooves provide necessary friction and traction to avoid pull-out. They are generally made from a metal. A screw is sometimes also known as cap screw or tap bolt. Note: Those who don’t… Read More »
Pelton turbine is a type of impulse turbine which converts water energy (kinetic and potential energy of water) into mechanical energy. Later this mechanical energy can be converted into electrical energy with the help of an electrical alternator. An impulse turbine is a type of turbine in which all the kinetic energy of water gets… Read More »
A hydroelectric power plant is a plant which converts energy of water (Kinetic and potential energy) into electricity (or electrical energy). These power plants operate on renewable and green energy. Which means they are not depleting any limited energy resource and at the same time not causing any harm (pollution) to our environment. Working of… Read More »
Rankine cycle is a vapor power cycle (a type of thermodynamic cycle) on which a steam based thermal power plant works. It consists of four processes Isobaric heat addition at boiler Isentropic expansion at turbine Isobaric heat rejection at condenser Isentropic compression at pump Now let’s understand Rankine cycle by relating it to steam based… Read More »
A thermal power plant is a power station which converts thermal energy to electrical energy. A thermal power plant is different from hydro power plant, where energy (kinetic and potential) of water is converted into electrical energy. For operating a thermal power plant, thermal energy can be obtained by burning fossil fuel, nuclear fuel, solar… Read More »
A steam engine is a type of heat engine in which working fluid is steam. It converts thermal energy of steam into mechanical work. Mechanical work can be used in generating electricity or propelling a locomotive. There are two types of Steam Engines. Steam is obtained from a boiler, where some fuel is burned to… Read More »
