If you have motor rpm shaft sizeblower pulley size how get blower rpm?

1. Motor RPM (revolutions per minute): This is the speed at which the motor is running.

2. Shaft Size: This is the diameter of the motor shaft.

3. Blower Pulley Size: This is the diameter of the pulley attached to the blower.

Here's the formula to calculate Blower RPM:

```

Blower RPM = (Motor RPM * Motor Pulley Size) / Blower Pulley Size

```

Let's say you have the following values:

- Motor RPM: 1750 RPM

- Motor Pulley Size: 4 inches

- Blower Pulley Size: 2 inches

Using the formula:

```

Blower RPM = (1750 RPM * 4 inches) / 2 inches

```

```

Blower RPM = 3500 RPM

```

Therefore, the blower will rotate at 3500 RPM.
