What Is A Impulse Turbine And Its Working

Today, you will gain all information about Impulse Turbines and its working. A human heart can be surprisingly replaced with two intrinsically complex turbines. It’s really a mind blowing fact right! Let me introduce the topic with turbine and will further proceed on to the body. A turbine is generally …

Abrasive Jet Machining Process And Applications

Abrasive jet machining uses a stream of fine grained abrasive mixed with air or some other carrier gas usually nitrogen at high pressure. Here abrasives used are sodium bicarbonate, glass power, silicon carbide are aluminum oxide. The particle size rages from 10m to 50µ. The smaller size particles are used to obtaining …

Types Of Breaks [Disc Break and Drum Break]

TYPES OF BREAKS :- A break is a device by means of which artificial frictional resistance is applied to a moving machine member, in order to retard or stop the motion of a machine. In the process of performing this function, the break absorbs either kinetic energy of the moving …

What Is Hydrodynamic Lubrication Bearings

Hydrodynamic Lubrication :- In hydrodynamic lubrication hydro means (liquid) and dynamic means (relative motion) it is the combination of both liquid and relative motion to reduce the friction. In hydrodynamic lubricated bearings, a thick film of lubricant is formed between the journal and the bearing. According to Reynolds their are some essential …

Lancashire Boiler Construction,working,Diagram

Lancashire Boiler :-Lancashire Boiler is a stationary,fire tube,internally fired, horizontal and natural circulation boiler. Lancashire boilers are reliable and bear over load. They are economical within their operating capacity. However, they are bulky and initially raise steam very slowly. Working pressure in lancashire boilers are in the range of 0.7 MPa …

Plastic Deformation (Slip And Twinning)

When a metal is stressed below its elastic limit, the resulting deformation or strain produced in the metal is temporary. This strain or deformation vanishes after the removal of stress and the metal goes back to the original dimensions. When it is stressed above the elastic limit, permanent deformation takes place …

Orthogonal And Oblique Cutting

Orthogonal Cutting In orthogonal cutting, the tool approaches the work piece with its cutting edge parallel to the uncut surface and at right angles to the direction of cutting. Thus tool approach angle and cutting edge inclination are Zero. This type of cutting is also known as Two-dimensional Cutting. Also …

Carnot Cycle Efficiency

This cycle was devised by carnot in 1824  and expanded by others in the 1830s and 1840s. carnot was the first scientist to analyze the problem of the efficiency of a heat engine, disregarding its mechanical details. He focussed mainly on the basic features of a heat engine. carnot cycle …
