Continuity equation can take the form

Explanation:

Continuity Equation

• It is based on the principle of conservation of mass.
• For a fluid flowing through a pipe at all the cross-section, the quantity of fluid per second is constant.
• The continuity equation is given as \({\rho _1}{A_1}{V_1} = \;{\rho _2}{A_2}{V_2}\)

Bernoulli’s Equation

• It is based on the principle of conservation of energy.
• For an ideal fluid flowing through a pipe at all the cross-section, the total energy would be constant.

Conservation of momentum

• It states that the net force acting on the fluid mass is equal to the change in momentum of flow per unit time in that direction.
