Bevel protractor is an instrument that has a graduated circular scale with one pivoted arm that is used for measuring or making off the angles.This instrument is capable of measuring angles with a least count of 5′ or 5 minutes.It is used to measure the angle of any workpiece. It is used for various objects like jigs.Sometimes the…
Pelton turbine is an impulse turbine named after an American engineer Lester A.Pelton.Pelton turbines are suitable for power extraction when water energy is available at a high head and low flow rate.In this type of turbine, the potential and the pressure energy of water is converted to kinetic energy. A nozzle is used which increases…
Ultrasonic Machining Process is a non-conventional machining process used for machining both conducting and non-conducting materials. This machining process can be used to machine such materials that cannot be machined by the conventional machining process. Ultrasonic Machining is mainly used in brittle materials.As the name suggests, the machining process makes use of ultrasonic vibrations in…
Chemical Machining is the process of removal of material from the workpiece using chemical reactions by immersing the workpiece into a chemical solution.Chemical Machining is a process used for metal removal purpose by dissolution in a controlled manner from the workpiece by the application of acidic or alkaline solution and this solution is called etchant.The chemical…
A spark ignition (SI) engine is a type of internal combustion engine in which the air-fuel mixture is ignited using a spark from the spark plug.The compression ratio of this engine is usually 6 to 10.The SI Engine is commonly used in light-duty vehicles like motorcycles, cars, etc.These engines are commonly known as gasoline engines…
This process is named as vapour compression refrigeration system because the vapour is compressed in this system to produce refrigeration.Vapour Compression Refrigeration Systems are the most commonly used refrigeration system among all the refrigeration system.In this system, the working fluid undergoes phase change twice from liquid to vapour and again from vapour to liquid.In this type of…
Impulse Turbine is defined as the turbine in which high-velocity jets of water or steam hits the blades of the turbine to rotate the turbine and produce electricity using this rotation. The impulse turbine is named so because it acts on the impulsive force created during the striking of the water jet to the turbine blades.In the impulse…
Axial Flow Compressor is a type of compressor in which the working fluid flows parallel to the axis of rotation of the rotor or axially.In this compressor, the working fluid is compressed by first accelerating the fluid and then diffusion it to increase its pressure. Compressors are mechanical devices used to compress fluids. In other words, they…
The differential manometer is used to measure the difference in pressure between two points in a pipe or in two pipes.The pressure at these two points is measured using two piezometers. This differential manometer is also used to measure the pressure difference between two containers. The differential manometer can be used to measure the flow…
Radial Drilling Machine is used to drill medium to large and heavy workpieces. This machine is used to drill holes in the given radial distance. It is mainly used when the component size is large in height. Radial Drilling machine is mainly made for drilling holes in heavy jobs or workpieces. Since heavy jobs cannot…
