Reduced Pressure of Real Gas using Reduced Wohl Equation given Reduced Parameters Solution

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

FIRST Step Consider the formula

P r = (\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 r = (\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 r = (\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 r = 0.0221408264187163

LAST Step Rounding Answer

∴

P r = 0.0221
