Answer 1

Explanation:

this is the answer of question

Answer 2

Answer:

The correct answer is dp/dt + J = 0.

Explanation:

• The expression for the continuity equation is dp/dt + J = 0.
• A continuity equation, also known as a transport equation, is a formula that describes the movement of a quantity.
• When applied to a conserved quantity, it is especially simple and powerful, but it can be generalised to any large quantity.
• It's called mass flow rate conservation. Because the density of an incompressible fluid is constant, the continuity equation is $A_{1} V_{1}$ = $A_{2} V_{2}$.
