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...
