Question

. What is equation of continuity? On which conservation law it is

​

Answer 1

Answer:

The equation proves the law of conservation of mass in fluid dynamics. Also, if the fluid is incompressible, the density will remain constant for steady flow. So, ρ1 =ρ2. This was the derivation of continuity equation.

Answer 2

Answer:

A continuity equation in physics is an equation that describes the transport of some quantity. ... For example, a weak version of the law of conservation of energy states that energy can neither be created nor destroyed—i.e., the total amount of energy in the universe is fixed.
