ANSWER:
Solution 105 HP
Step 1 of 5
We have to find the pressure of the methane gas of mass 8.35 kg in a tank of volume 0.1 m3 at 250 K using ideal gas equation, Redlich-Kwong EOS, and the methane table.
The pressure of the methane gas from ideal gas equation is given by
where,
gas constant
K
m3
kg
The gas constant for methane from the Table A-5 in the book is
kJ/kgK
Thus,
Therefore, the pressure of the methane gas using ideal gas equation is 10820 kPa.
