The image above represent angular velocity.

To compute the angular velocity, one essential parameter is needed and its parameter is **Number of Revolutions per Minute (N).**

The formula for calculating angular velocity:

ω = ^{2πN} / _{60}

Where;

ω = Angular velocity

N = Number of revolutions per minute

Let’s solve an example;

Find the Angular Velocity with a number of revolutions per minute as 60.

This implies that;

N = Number of revolutions per minute = 60

ω = ^{2πN} / _{60}

ω = ^{2 x π x 24} / _{60}

ω = ^{150.816}/ _{60}

ω = 2.5136

Therefore, the **angular velocity** is **2.5136 rad/s.**

**Calculating the Number of Revolutions per Minute when Angular Velocity is Given.**

N = ^{ω60} / _{2π}

Where;

N = Number of revolutions per minute

ω = Angular velocity

Let’s solve an example;

With an angular velocity of 40. Find the number of revolutions per minute?

This implies that;

ω = Angular velocity = 40

N = ^{ω60} / _{2π}

N = ^{40 x 60} / _{6.284}

N = ^{2400} / _{6.284}

N = 381.9

Therefore, the **number of revolutions per minute** is **381.9 min.**
