Que: What is the function of governor?

       
Ans: A governor is essentially a speed-sensitive device, designed to 
maintain a constant engine speed regardless  of load variation.  
 Since all governors  used on diesel engines  control engine 
speed through the regulation of the quantity of fuel delivered to 
the cylinders, these governors may be classified as 
speed-regulating governors.
What is the function of air preheater in power plant?

It is usea for heated the air before entering the combustion chamber with use of exhaust gas heat.
what is the meaning of "API 5l"?
Which one is best engine 2 stroke or 4 stroke?



As per performance 4 stroke is better because of its efficiency and as power 2 stroke is better because it generate more power for same volume.

Que: Definition for RADIUS OF GYRATION?



Ans: Radius of gyration means Underroot value of moment of inertia(I) and area(A).
Mathematically radius of gyration(K) is given by
K=I/A but I and A are in underroot sign.
Que: What is fusible plug? Why it is used?












Ans: Fusible plug is used as a accessory in boilers. It is used for the proper working of boilers.
Fusible plug is an device used for safety of the boiler after a certain temperature it melts and prevents further increase in temperature of the boiler.
Que: What is Priming?















Ans:  Priming is the process of filling water in centrifugal pump suction strainer to casing upto the delivery valve or priming point. It will remove the air from the suction side of the pump. In centrifugal pump the liquid pumped is directly propotional to the density of the working fluid. If air is present its density is less than water so water will not suck to the pump suction.
