Here is how the Reduced Pressure equation looks like.

1.1E-6 = \frac{38.4}{3.4E+7}

1.1E-6 = \frac{38.4Pa}{3.4E+7Pa}

1.1E-6 = \frac{38.4}{3.4E+7}

Reduced Pressure Solution

Follow our step by step solution on how to calculate Reduced Pressure?

FIRST Step Consider the formula

P r = \frac{p}{P c}

Next Step Substitute values of Variables

∴

P r = \frac{38.4Pa}{3.4E+7Pa}

Next Step Prepare to Evaluate

∴

P r = \frac{38.4}{3.4E+7}

Next Step Evaluate

∴

P r = 1.14626865671642E-06

LAST Step Rounding Answer

∴

P r = 1.1E-6
