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

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

FIRST Step Consider the formula

P, c = \frac{(\frac{[R] \cdot T rg}{V' m - b}) - (\frac{a}{T rg \cdot V' m \cdot (V' m - b)}) + (\frac{c}{({T rg}^{2}) \cdot ({V' m}^{3})})}{P r}

Next Step Substitute values of Variables

∴

P, c = \frac{(\frac{[R] \cdot 300K}{0.0224m³ - 0.0062}) - (\frac{266}{300K \cdot 0.0224m³ \cdot (0.0224m³ - 0.0062)}) + (\frac{21}{({300K}^{2}) \cdot ({0.0224m³}^{3})})}{0.0024}

Next Step Substitute values of Constants

∴

P, c = \frac{(\frac{8.3145 \cdot 300K}{0.0224m³ - 0.0062}) - (\frac{266}{300K \cdot 0.0224m³ \cdot (0.0224m³ - 0.0062)}) + (\frac{21}{({300K}^{2}) \cdot ({0.0224m³}^{3})})}{0.0024}

Next Step Prepare to Evaluate

∴

P, c = \frac{(\frac{8.3145 \cdot 300}{0.0224 - 0.0062}) - (\frac{266}{300 \cdot 0.0224 \cdot (0.0224 - 0.0062)}) + (\frac{21}{(300^{2}) \cdot ({0.0224}^{3})})}{0.0024}

Next Step Evaluate

∴

P, c = 63340834.1142123Pa

LAST Step Rounding Answer

∴

P, c = 6.3E+7Pa
