Basic terminology of fluid mechanics  Steady flow : In this flow velocity of fluid particle don't change with time at fixed point of fluid is called steady flow. Unsteady flow: In this flow velocity of particle change with time at fixed point of fluid is called unsteady fluid . Uniform flow : In this flow the magnitude of flow don't change (same ) at point of fluid . Non-uniform flow: In this flow the magnitude of flow  change (different) at point of fluid . Laminar flow :   In this flow fluid particle move in smooth and regular in motion is called laminar fluid is called laminar fluid and it is also  called steam line flow . Turbulent flow :   In this flow fluid particle move in randomly  and irregular  in motion is called laminar fluid is called laminar fluid. Continuity equation : According to this law the inlet fluid is equal to outlet fluid this law based on the conservation of mass . Q = p.A.V   Where the Q is discharge of fluid and p is...

Interview questions for mechanical engineering

Q.  What is elasticity?  Ans. It is the propertyof material where apply deforming force on the body  so body is deformed,  it will regain its original shape after removing deforming force.  Q. What is plasticity?  Ans. It is the property of material where apply deforming force on the body so it will permanently deformed after removing deforming force.  Q. What's brittleness?  Ans. It is the property which is distortion  of material when applying impact load  or it will break in small parts.  Compressive strengh is high and tensile strength is low.  Q. What is creep?  Ans. It is the property of material which have slow permanent deformation  within temperature along long time.  It's occure in belt  Q. What's toughness?  Ans.is the property of material,Which is resist the high impact load for short time. That is callled toughness.  Q. What's Malleability  ??  Ans.  It the property of m...

    Air standard  cycle :                                                         Diesel cycle : Diesel engine work on the diesel cycle and it consist of two isentropic process and one isobaric process , one  isochoric process .     Isentropic process : Compression process : Air is compress at isentropic process  Isobaric process : Heat addition , increasing pressure of gas at isobaric process  Isentropic process : Expansion process , Where fuel and compressed air contact so fuel will burn and produce heat and pressure so power will generate . Isochoric process : Where the exhausted gas is remove from combustion chamber at isochoric process Below diagram between pressure and volume & entropy and temperature   Efficiency of diesel cycle : Output / Input Where the r is compression ra...
