I have a stream ($10,000$ $m^3/d$) of inert gas and steam. The temperature of the stream is $195$ $^oC$, and the absolute pressure is $1455$ $kPa$.

I am trying to find the amount of steam that can be present in the system. I can assume $100\%$ quality saturated steam.

Would I be correct in approximating the steam fraction to be: $P_{sat@T}$ / $P_{stream}$

At $195$ $^oC$, the $P_{sat}$ of steam is $1398$ $kPa$. Therefore the fraction of steam is: $1398/1455$ $=$ $96\%$.

I can then find the volume of steam: $0.96*10,000$ $=$ $9,600$ $m^3/d$.

Is my reasoning correct. Any other ways to calculate this question?
