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...

Kinematic theory of gas :                 Pressure is produce due to gas molecular collision               Average kinetic energy of gas is depend on molecule of gas               Kinematic energy of gas (K) = 1/2.MV2 = 3/2 kT Where m is the mass of gas and k is Boltzmann constant , V is velocity of gas molecule and T is the temperature of gas. Thermal expansion : Material expand due to temperature rise length will also increase  L = l.t.(apha) Where alpha is coefficient of thermal  expansion  Stefan Boltzmann constant :   first statement : Power is directly proportional to fourth power of absolute temperature  P =kT4 Second law of thermodynamics : Power is directly proportional to area . P = kA So                P =sigma .AT4     Entropy : It is the property of which show the degree of randomnes...
