Hey, have a thermodynamics problem involving the first law that I need help with.

"A water-ﬁlled reactor with a volume of 1 m^3 is at
20 MPa and 360◦C and is placed inside a contain-
ment room, as shown in Fig. P3.101. The room
is well insulated and initially evacuated. Due to
a failure, the reactor ruptures and the water ﬁlls
the containment room. Find the minimum room
volume so that the ﬁnal pressure does not exceed
200 kPa."

The answer is "287.7 m^3"

Also, I would like to say that I don't need a full solution; I just want a nudge in the right direction. Thanks.

nottim · Answer

im on the same subject, but im a little frazzled from my work, so ill just repeat the basics.
Write out your givens
write out your required formula
draw a diagram especially for classical mechanics
input values into formula and solve

I still have no idea how to solve this haha
