Blank Diameter from Percent Reduction Solution

Follow our step by step solution on how to calculate Blank Diameter from Percent Reduction?

FIRST Step Consider the formula

D b = d s \cdot {(1 - \frac{PR %}{100})}^{- 1}

Next Step Substitute values of Variables

∴

D b = 80mm \cdot {(1 - \frac{5}{100})}^{- 1}

Next Step Convert Units

∴

D b = 0.08m \cdot {(1 - \frac{5}{100})}^{- 1}

Next Step Prepare to Evaluate

∴

D b = 0.08 \cdot {(1 - \frac{5}{100})}^{- 1}

Next Step Evaluate

∴

D b = 0.0842105263157895m

Next Step Convert to Output's Unit

∴

D b = 84.2105263157895mm

LAST Step Rounding Answer

∴

D b = 84.2105mm
