Step 12: Find the corrected power rate and number of v-belts required; We found the power rate. of the v-belt in step 6. Multiply the correction factors that you found in step 11 with the power rate to find the corrected power rate of the selected standard v-belt. Divide the design power with the corrected power rate of the v-belt.

The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from Tables 9 through 12 by the arc of contact correction factor and by the length correction factor.
