(Answer the following questions briefly and to the point :)
State the Principle of Continuity of fluids.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Concept**: The Principle of Continuity of fluids is based on the conservation of mass in fluid dynamics. It applies to incompressible fluids flowing through a tube of varying cross-section.

2. **Statement of the Principle**: The principle states that for an ideal fluid flowing in a streamline flow through a tube of non-uniform cross-section, the product of the cross-sectional area (A) and the fluid velocity (V) at any point along the tube remains constant.

3. **Mathematical Expression**: This can be mathematically expressed as:
\[
