The equation of continuity is based on the principle of conservation of mass. It states that the mass of a fluid flowing through a pipe or other conduit remains constant. This means that the mass of fluid entering the conduit must equal the mass of fluid leaving the conduit. The equation of continuity can be used to calculate the velocity of a fluid, the pressure of a fluid, and the flow rate of a fluid.
The principle of conservation of mass states that mass can neither be created nor destroyed. This means that the total mass of an isolated system remains constant over time. The equation of continuity is a mathematical expression of the principle of conservation of mass. It can be used to calculate the mass of a fluid flowing through a pipe or other conduit.
The principle of conservation of energy states that energy can neither be created nor destroyed. This means that the total energy of an isolated system remains constant over time. The equation of continuity cannot be used to calculate the energy of a fluid flowing through a pipe or other conduit.
The principle of conservation of momentum states that momentum can neither be created nor destroyed. This means that the total momentum of an isolated system remains constant over time. The equation of continuity cannot be used to calculate the momentum of a fluid flowing through a pipe or other conduit.
