Q. The continuity equation is based on the principle of:

निरंतरता समीकरण निम्नलिखित सिद्धांत पर आधारित है:

A
Conservation of energy
ऊर्जा संरक्षण
B
Conservation of mass
संरक्षण का मास
C
Conservation of momentum
संवेग का संरक्षण
D
Conservation of pressure
दबाव का संरक्षण

Explanation

The continuity equation ensures that mass is conserved in a fluid system. In differential form, for incompressible flow:

V=0\nabla \cdot \vec{V} = 0

In integral form:

A1V1=A2V2A_1V_1 = A_2V_2
