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

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

FIRST Step Consider the formula

P r = \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, c}

Next Step Substitute values of Variables

∴

P r = \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})})}{4.6E+6Pa}

Next Step Substitute values of Constants

∴

P r = \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})})}{4.6E+6Pa}

Next Step Prepare to Evaluate

∴

P r = \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})})}{4.6E+6}

Next Step Evaluate

∴

P r = 0.0330473917117629

LAST Step Rounding Answer

∴

P r = 0.033
