What do you understand by laminar flow of a liquid ?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Laminar Flow**:
Laminar flow refers to a type of fluid flow in which the fluid moves in parallel layers, with minimal disruption between them. This means that each layer of fluid slides past the adjacent layer smoothly and uniformly.

2. **Characteristics of Laminar Flow**:
- **Smooth Movement**: In laminar flow, the fluid travels smoothly without any chaotic changes in velocity or direction.
- **Regular Path**: The flow follows a consistent and predictable path, which can be visualized as layers of fluid moving in straight lines.
