The conservation of mass flow rate states that the mass of a fluid entering a system must be equal to the mass leaving the system, assuming no mass is being created or destroyed within the system.
Bernoulli's equation states that in an ideal fluid flowing along a streamline, the sum of its pressure energy, kinetic energy, and gravitational potential energy per unit volume remains constant.
The continuity equation states that for an incompressible fluid, the product of its cross-sectional area and velocity remains constant along any streamline. It helps describe how changes in area affect fluid velocity and vice versa.
