stste the principal of continuity of fluid
Answers
Continuity principle, orcontinuity equation, Principle of fluid mechanics. Stated simply, what flows into a defined volume in a defined time, minus what flows out of that volume in that time, must accumulate in that volume.
If the sign of the accumulation is negative, then the material in that volume is being depleted. The principle is a consequence of the law of conservation of mass. The behaviour of fluids in motion is fully described by this equation, plus a second equation, based on the second of Newton’s laws of motion, and a third equation, based on the conservation of energy.
According to this principal, when an incomprssible and nonviscous flow in streamlined motion through a tube of non uniform cross section area then the product of the area of cross section and the velocity of flow is same at every point of the tube
