How many revolutions will a 5" id x 5/8 id pulley on a electric motor shaft rotating at 1700 rpms.

To calculate the number of revolutions that the pulley on the electric motor shaft will make, we need to consider the relationship between the pulley's diameter and the motor's rotation speed.

First, we need to convert the pulley's diameter from inches to feet. Since there are 12 inches in a foot, the pulley's diameter in feet would be 5/12 feet.

Next, we can use the formula to calculate the pulley's circumference:

Circumference = π × diameter

Since we're using feet for the diameter, we can use the value of π as approximately 3.14 to calculate the circumference.

Circumference = 3.14 × (5/12) feet

Now, we know that one revolution of the pulley corresponds to one complete circumference. Therefore, the number of revolutions can be calculated by dividing the motor's rotation speed by the pulley's circumference.

Number of Revolutions = Motor RPM / Pulley Circumference

Number of Revolutions = 1700 RPM / Circumference

Substituting the calculated circumference, we get:

Number of Revolutions = 1700 RPM / (3.14 × (5/12) feet)

Simplifying the equation:

Number of Revolutions = 1700 RPM / (3.14 × (5/12) feet)
Number of Revolutions ≈ 1700 RPM / (0.523 feet)
Number of Revolutions ≈ 3251.43 revolutions

Therefore, the 5" ID x 5/8" ID pulley on the electric motor will make approximately 3251.43 revolutions.
