Mixture of different gases at different temperatures

Homework Statement

Hello. I have problém with this system. Mixture of two gases. How can i determine temperature T3?
Gas 1 (dry air) - I know T1, p1, m1
Gas 2 (water steam) - I know T2, p2, m2

Output (mixture) P3, (m1+m2); p3<p1;p3<p2

Homework Equations

The Attempt at a Solution

Is it possible to use this solution?
m1*c1*t1+m2*c2*t2=m1*c1'*t3+m2*c2'*t3
from the software tables
c1=function(p1;t1)
c1'=function(p3;t3)
c2=function(p2;t2)

c2'=function(p3;t3)​

?

Or i should use Daltons law to determine different partial pressure in c1' and c2'?

Excuse my English. I am working on it :)

The answer depends on the details of the process that is employed.

This is a process in the steam turbine seals. There is one "tube" with air, second "tube" with steam and they both point into the chamber. In chamber is vacuum (vacuum is made by vacuum-pump)

You have two streams flowing into a closed chamber of fixed volume that is initially under zero absolute pressure?

Sorry my mistake. p1=p2=p3 chamber is opened.

Sorry my mistake. p1=p2=p3 chamber is opened.

Please draw a schematic diagram.
