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...
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...
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...
