The formula shown in the image is calculating velocity $v$ using the equation:

$v = \frac{\pi \cdot d_{w1} \cdot n_1}{60000}$

where:

• $d_{w1}$ seems to represent a diameter (possibly of a wheel or a rotating object).
• $n_1$ is likely the rotational speed in revolutions per minute (RPM).
• $60000$ is used to convert from RPM to a linear velocity (in meters per second).

In the example: $v = \frac{\pi \cdot 26.846 \cdot 1450}{60000}$

This equals approximately: $v \approx 2.038 \, \text{m/s}$

This result, $2.038 \, \text{m/s}$, is the calculated velocity.

Here are 5 related questions to consider:

1. What are the units of $d_{w1}$ and $n_1$ in the given formula?
2. How does multiplying by $\pi$ affect the relationship between rotational speed and velocity?
3. What physical scenario might this formula describe (e.g., wheel on a vehicle)?
4. Why is the number 60000 used to convert units in this formula?
5. What adjustments would be needed if $n_1$ were in radians per second instead of RPM?

Tip: Always ensure unit consistency when applying formulas, especially when converting between angular and linear velocities.
