Reference Tool Life given Production Cost per Component Solution

Follow our step by step solution on how to calculate Reference Tool Life given Production Cost per Component?

FIRST Step Consider the formula

L ref = \frac{(\frac{K}{{V ref}^{\frac{1}{n}}}) \cdot (M \cdot t c + C t) \cdot (V^{\frac{1 - n}{n}})}{C p - M \cdot (NPT + \frac{K}{V})}

Next Step Substitute values of Variables

∴

L ref = \frac{(\frac{203.0681m}{{0.76m/s}^{\frac{1}{0.125}}}) \cdot (0.0028 \cdot 5min + 100) \cdot ({0.28m/s}^{\frac{1 - 0.125}{0.125}})}{5.6553 - 0.0028 \cdot (20min + \frac{203.0681m}{0.28m/s})}

Next Step Convert Units

∴

L ref = \frac{(\frac{203.0681m}{{0.76m/s}^{\frac{1}{0.125}}}) \cdot (0.0028 \cdot 300s + 100) \cdot ({0.28m/s}^{\frac{1 - 0.125}{0.125}})}{5.6553 - 0.0028 \cdot (1200s + \frac{203.0681m}{0.28m/s})}

Next Step Prepare to Evaluate

∴

L ref = \frac{(\frac{203.0681}{{0.76}^{\frac{1}{0.125}}}) \cdot (0.0028 \cdot 300 + 100) \cdot ({0.28}^{\frac{1 - 0.125}{0.125}})}{5.6553 - 0.0028 \cdot (1200 + \frac{203.0681}{0.28})}

Next Step Evaluate

∴

L ref = 120.000319201788s

Next Step Convert to Output's Unit

∴

L ref = 2.0000053200298min

LAST Step Rounding Answer

∴

L ref = 2min
