Pressure of Real Gas using Wohl Equation Solution

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

FIRST Step Consider the formula

P rg = (\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})})

Next Step Substitute values of Variables

∴

P rg = (\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})})

Next Step Substitute values of Constants

∴

P rg = (\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})})

Next Step Prepare to Evaluate

∴

P rg = (\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})})

Next Step Evaluate

∴

P rg = 152018.00187411Pa

LAST Step Rounding Answer

∴

P rg = 152018.0019Pa
