MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-1.)Definition of Octane Number and Cetane Number?Ans.Octane No.- Octane number is defined as the percentage, by volume, of iso octane in the mixture of iso octane and hheptane. It is the measure of rating of SI engine.Cetane No.- Cetane number is defined as the percentage, by volume, of n-cetane in the mixture of n-cetane and alpha methylnaphthalene. It is the measure of rating of CI engine.2.)Which Pump is more Efficient Centrifugal Pump or Reciprocating Pump?Ans. Centrifugal pump. Because flow rate is higher compared to reciprocating pump. Flow is smooth and it requires less space toinstall. Lower initial cost and lower maintenance cost.3.)How a Diesel Engine Works as Generator?Ans.Diesel engine is a prime mover, for a generator, pump,and for vehicles etc. generator is connected to engine by shaft.mostly in thermal power plat,there is an engine is used to drive generator to generate power.4.)Compare Brayton Cycle and Otto Cycle?Ans. The heat addition and rejection processes in Otto cycle are of constant volume, whereas in Brayton cycle, they are ofconstant pressure.-Otto cycle is the ideal cycle for spark ignition engines.-Brayton cycle is the ideal cycle for gas power turbines.For more interview question join now.
