Initial Temperature (T1)=400F=(5/9)(400-32)=204.44 C
If steam is heated at constant volume (in a rigid vessel) to teach critical point(Tc=374C),
From steam table :
At critical point specific volume(v2)=0.003105m3/kg
Therefore specific volume at initial state(v1)=(v2)=0.003105 m3/kg
vf=0.001164 m3/kg, vg=0.11508 m3/kg
Quality of steam(X) at T1=204.44 C is given by
Ans: Quality of steam at T1=4000F is X=0.01711
Dear Jevens Mark,

is no guarantee of answering certain question but we are doing our best. And if answer
is published it means it was attentively checked by experts. You can try it yourself by
publishing your question. Although if you have serious assignment that requires large amount
of work and hence cannot be done for free you can submit it as assignment and our
experts will surely assist you.
How did you get the T2=374C?
