Pressure using Virial Equation of State Solution

Follow our step by step solution on how to calculate Pressure using Virial Equation of State?

FIRST Step Consider the formula

P abs = (\frac{1}{v}) \cdot (([R] \cdot T) + (P \cdot B))

Next Step Substitute values of Variables

∴

P abs = (\frac{1}{16.7m³/kg}) \cdot (([R] \cdot 85K) + (38.4Pa \cdot 2.2m³/kg))

Next Step Substitute values of Constants

∴

P abs = (\frac{1}{16.7m³/kg}) \cdot ((8.3145 \cdot 85K) + (38.4Pa \cdot 2.2m³/kg))

Next Step Prepare to Evaluate

∴

P abs = (\frac{1}{16.7}) \cdot ((8.3145 \cdot 85) + (38.4 \cdot 2.2))

Next Step Evaluate

∴

P abs = 47.3778037450913Pa

LAST Step Rounding Answer

∴

P abs = 47.3778Pa
