1-10. Determine the specific weight of carbon dioxide when the
temperature is 100°C and the absolute pressure is 400 kPa.

SOLUTION
From the table in Appendix A, the gas constant for carbon dioxide is R = 188.9 J / kg • K.
R

p=p T
400(103) N/m2 = p(188.9 J/kg • K)(100° + 273) K p =

5.677 kg / m3
The specific weight of carbon dioxide is
g = pg = (5.677 kg / m3)(9.81 m / s2)
= 55.7 N/m3

Ans.

Ans:
55.7 N / m3
