Basic Mechanical Engineering Question and Answer

1.       What is Kelvi-Plank law? Kelvi-Plank law is state that it is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce a net amount of work. 100 % efficient heat engine cannot find 2.       What is the function of diffuser in Compressor? In Fluid Mechanics Bernoulli’s Equation pays a vital role to learn more about diffuser performance. Diffuser is one of the components in a simple centrifugal compressor. Downstream of the impeller in the flow path, diffuser mainly work as converter where it high velocity to low velocity (mainly kinetic energy convert). 3.       What is the relation between C and K? Relation between Kelvin and Celsious is   K = °C + 273.15   °C = K - 273.15 4.       What is the Aeroplane compressor system? There are three types of air compressor used in Aeropalne compressor system a.        Axial Flow b.       Centrifugal flow c.        Centrifug
