https://www.che.iitb.ac.in/faculty/madhu/CL152/Handouts/Handout%206.pdf Do you think any of these formulas would help?

No I don't have any of that information. What I've said until now it's all the information they gave me.

It's exactly what my first post on this thread says. Do you think that knowing the initial temperature and pressure of the water and that it was transferred 58w to it in a 10m2 area will give us the final temperature and pressure of water? It also asks to: b) Characterize the flows that leave...

It was from the problem, I didnt calculate it.

Yes I'm sure so. Although I have to do it using a program called Aspen, don't know if you are familiar with it, and maybe with the tips you gave me and using the program it can help finding the miss information.

I think its a superheated vapor.

So I found this table. 7 bar equals 700 kPa, so this is the part of the table that would matter for that pressure. Would I have to replace the H in the equation you showed me to calculate the mass flow rate?

How do I calculate ##h_{in}## and ##h_{out}##? I know that h=u+PV but I don't know the specific internal energy (u) or the volume.

Hello. Yes it's a saturated liquid under these conditions, and yes I think it will all evaporate. It's not a homework problem, it's a project I have to do for University at the end of the semester. I have few time to do it and I have searched all over the internet and I can't solve it so I would...

I have to do a project using Aspen and need to do some math before hand. Can you please help me? Here's the problem: A heat exchanger with 10 m2 of heat transfer area is provided to supply 58 kW to a water stream available at 15 ° C and 1 bar. The available hot fluid is freon-12 at 32 ° C and 7...
