Hey, guys. I am currently in a Thermo I class and have ran into a problem that has me completely stumped. I have worked in numerous different ways and anything I come up with doesn't seem to make since or be realistic. Here's the question:
Two rigid vessels are connected by a small valve and tubing. Both are of negligible size. Vessel 1 contains .8m3 of water at 650kPa at a quality of 50%. Vessel 2 contains .4m3 of water at 400kPa and 250ºC. If the valve is oped and both vessels come to equilibrium, determine the final equilibrium pressure and the amount of heat transfer when the system reaches thermal equilibrium with he surroundings which are at 50˚C.
I have currently been using the continuity equations and using steam tables to get the values that I need. My Prof said I was on the right track but wasn't very helpful at all during our session. I hope you guys can give me some hints. Thanks.
