Next Step Convert Units

∴

C j = \sqrt{(\frac{2 \cdot 24.6K \cdot 8.3145 \cdot 1.33}{0.0065kg/mol} / (1.33 - 1)) \cdot (1 - {(\frac{2.1E+6Pa}{6.5E+6Pa})}^{1 - \frac{1}{1.33}})}

Next Step Prepare to Evaluate

∴

C j = \sqrt{(\frac{2 \cdot 24.6 \cdot 8.3145 \cdot 1.33}{0.0065} / (1.33 - 1)) \cdot (1 - {(\frac{2.1E+6}{6.5E+6})}^{1 - \frac{1}{1.33}})}

Next Step Evaluate

∴

C j = 248.869960344833m/s

LAST Step Rounding Answer

∴

C j = 248.87m/s
