Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

### Airflow Dynamics Between a Circular Disk and a Cone

Air flows from a pipe into a region between a circular disk and a cone, as depicted in the accompanying diagram. The fluid velocity in the gap between the disk and the cone can be approximated using the formula:

\[ V = V_0 \frac{R^2}{r^2} \]

**Where:**

- \( R \) is the radius of the disk.
- \( r \) is the radial coordinate.
- \( V_0 \) is the fluid velocity at the edge of the disk.

**Problem Statement:**
Determine the acceleration for the following conditions:
- \( r = 0.5 \, \text{ft} \)
- \( r = 2.0 \, \text{ft} \)

**Given:**
- \( V_0 = 4 \, \text{ft/s} \)
- \( R = 3 \, \text{ft} \)

### Diagram Explanation

The diagram illustrates a vertical pipe allowing airflow into a horizontal space between a circular disk at the bottom and an upward-facing cone. The flow direction is indicated by arrows.

**Elements:**
- **Pipe:** Air flows vertically downward from the pipe.
- **Disk:** A flat, circular surface at the bottom. Its radius is \( R \).
- **Cone:** Positioned above the disk with a slanted surface, allowing airflow in the radial direction.
- **Flow Vectors:** Arrows indicate the flow path and velocity direction.

**Radial Distance (r):** The distance from the disk's center to a point where velocity \( V \) is being measured.

### Calculation Objectives
Using the velocity formula, calculate the precise fluid velocity and acceleration for specified radial distances to understand how velocity changes impact acceleration in this configuration.
