Pitch diameter of smaller pulley given pitch diameter of big pulley Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter of Small Pulley = Diameter of Big Pulley*(Speed of Larger Pulley/Speed of Smaller Pulley)
d = D*(n₂/n₁)
This formula uses 4 Variables

Variables Used

Diameter of Small Pulley - (Measured in Meter) - Diameter of Small Pulley is the distance from side to side of the flat of the Small pulley.
Diameter of Big Pulley - (Measured in Meter) - Diameter of Big Pulley is the distance from side to side of the flat of the Big pulley.
Speed of Larger Pulley - (Measured in Radian per Second) - Speed of Larger Pulley can be defined as the number of revolutions the larger sized pulley makes in a given unit of time.
Speed of Smaller Pulley - (Measured in Radian per Second) - Speed of Smaller Pulley can be defined as the number of revolutions the smaller-sized pulley makes in a given unit of time.

STEP 1: Convert Input(s) to Base Unit

Diameter of Big Pulley: 810 Millimeter --> 0.81 Meter (Check conversion here)
Speed of Larger Pulley: 1920 Revolution per Minute --> 201.061929819508 Radian per Second (Check conversion here)
Speed of Smaller Pulley: 640 Revolution per Minute --> 67.0206432731694 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d = D*(n₂/n₁) --> 0.81*(201.061929819508/67.0206432731694)

Evaluating ... ...

d = 2.43

STEP 3: Convert Result to Output's Unit

2.43 Meter -->2430 Millimeter (Check conversion here)

FINAL ANSWER

2430 Millimeter <-- Diameter of Small Pulley

(Calculation completed in 00.004 seconds)
