Number of Jobs Revolution per Unit Time Solution

Follow our step by step solution on how to calculate Number of Jobs Revolution per Unit Time?

FIRST Step Consider the formula

N = \frac{V c}{π \cdot d i}

Next Step Substitute values of Variables

∴

N = \frac{6.9848m/s}{π \cdot 31mm}

Next Step Substitute values of Constants

∴

N = \frac{6.9848m/s}{3.1416 \cdot 31mm}

Next Step Convert Units

∴

N = \frac{6.9848m/s}{3.1416 \cdot 0.031m}

Next Step Prepare to Evaluate

∴

N = \frac{6.9848}{3.1416 \cdot 0.031}

Next Step Evaluate

∴

N = 71.7204643362997rad/s

Next Step Convert to Output's Unit

∴

N = 684.879985232961rev/min

LAST Step Rounding Answer

∴

N = 684.88rev/min
