1. What is the RPM to Velocity Formula?

The RPM to Velocity formula calculates the linear velocity of a point on a rotating object based on its rotational speed (RPM) and the distance from the center of rotation (diameter). This is particularly useful in mechanical engineering and physics applications.

2. How Does the Calculator Work?

The calculator uses the velocity formula:

Where:

• \( v \) — Linear velocity (m/s)
• \( RPM \) — Rotations per minute (rev/min)
• \( \pi \) — Mathematical constant pi (≈3.14159)
• \( d \) — Diameter (m)

Explanation: The formula converts rotational speed to linear velocity by accounting for the circumference of rotation and converting minutes to seconds.

3. Importance of Velocity Calculation

Details: Calculating linear velocity from RPM is essential in designing mechanical systems, analyzing motion in rotating machinery, and understanding the relationship between rotational and linear motion in various engineering applications.

4. Using the Calculator

Tips: Enter RPM in revolutions per minute and diameter in meters. Both values must be positive numbers. The calculator will output velocity in meters per second.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 60 in the formula?
A: We divide by 60 to convert from minutes to seconds, as velocity is typically measured in meters per second.

Q2: Can I use radius instead of diameter?
A: Yes, but you would need to adjust the formula to: v = (RPM × π × 2 × r) / 60, where r is the radius.

Q3: What are typical applications of this calculation?
A: This calculation is used in conveyor systems, vehicle wheel speed calculations, machining operations, and any application involving rotating components.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for ideal conditions, but real-world factors like slippage and deformation may affect actual velocity.

Q5: Can this be used for angular velocity?
A: No, this calculates linear velocity. For angular velocity, use ω = RPM × 2π / 60 (radians per second).
