Actual Pressure of Real Gas using Reduced Wohl Equation given Reduced and Critical Parameters Solution

Follow our step by step solution on how to calculate Actual Pressure of Real Gas using Reduced Wohl Equation given Reduced and Critical Parameters?

FIRST Step Consider the formula

P rg = P, c \cdot ((\frac{15 \cdot T r}{4 \cdot (V' r - (\frac{1}{4}))}) - (\frac{6}{T r \cdot V' r \cdot (V' r - (\frac{1}{4}))}) + (\frac{4}{({T r}^{2}) \cdot ({V' r}^{3})}))

Next Step Substitute values of Variables

∴

P rg = 4.6E+6Pa \cdot ((\frac{15 \cdot 1.46}{4 \cdot (246.78 - (\frac{1}{4}))}) - (\frac{6}{1.46 \cdot 246.78 \cdot (246.78 - (\frac{1}{4}))}) + (\frac{4}{({1.46}^{2}) \cdot ({246.78}^{3})}))

Next Step Prepare to Evaluate

∴

P rg = 4.6E+6 \cdot ((\frac{15 \cdot 1.46}{4 \cdot (246.78 - (\frac{1}{4}))}) - (\frac{6}{1.46 \cdot 246.78 \cdot (246.78 - (\frac{1}{4}))}) + (\frac{4}{({1.46}^{2}) \cdot ({246.78}^{3})}))

Next Step Evaluate

∴

P rg = 101847.801526095Pa

LAST Step Rounding Answer

∴

P rg = 101847.8015Pa
