Number of Jets Solution

Follow our step by step solution on how to calculate Number of Jets?

FIRST Step Consider the formula

n J = {(\frac{N SMJ}{N SSJ})}^{2}

Next Step Substitute values of Variables

∴

n J = {(\frac{73rev/min}{30rev/min})}^{2}

Next Step Convert Units

∴

n J = {(\frac{8rad/s}{3rad/s})}^{2}

Next Step Prepare to Evaluate

∴

n J = {(\frac{8}{3})}^{2}

Next Step Evaluate

∴

n J = 6.00086677777779

LAST Step Rounding Answer

∴

n J = 6
