The various advantages of using the steam turbine over steam engine are as follows: It requires less shaft workspace compared to the steam engine. The absence of various ..
In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed ..
Various specific terms describe the characteristics and quality of measuring instruments, defined as follows: Accuracy: The degree of agreement of the measured dimension ..
A centrifugal compressor is one of its class machines in producing a pressure rise and is known as turbo-compressors. In centrifugal compressors, energy is transferred ..
The First law of thermodynamics states that energy is neither created nor destroyed. Thus the total energy of the universe is a constant. However, energy can certainly ..
In Water Jet Machining (WJM) process, water jets alone (without abrasives) can be used for cutting. Thin jets of high pressure and high velocity have been ..
The simple Rankine cycle is also a reversible cycle. Consider the idealized four-steady-state-process cycle in which state 1 is saturated liquid and state ..
Several techniques are used to improve the surface properties of manufactured components mechanically. The most common methods are listed and described under: Shot ..
In fluid mechanics, the pressure results from a normal compressive force acting on an area. The pressure ‘P’ is defined as force (F) per unit area (A). ..
