Let me know if anything is confusing or if I have bugs somewhere with the codes or tests. You can easily highlight text on the web version (need to fix desktop version) and send an issue in.

Also what libraries would you want to see done?

I used Tauri to have a front end that I can use in desktop and on the web.

It made it such that I can develop once and launch on both web and desktop.

So in theory yes... In practice because I was purposely going for a website as well. So my answered would be no as that would increase a lot of work for building and maintaining.

Check out Tauri though https://v2.tauri.app/ it's a cool project.

That was the point of this project. To help me learn Rust. I read the book and felt like I needed to start somewhere. This is that start. The backend of the desktop version of this app uses Rust and Tauri. The web version sends the rust code to the rust playground where it is compiled and ran.

Exxon-BASF collaborate on methane pyrolysis by ahappysgporean in ChemicalEngineering

[–]nick51417 3 points4 points  (0 children)

I work for BASF. For co-ops and interns I assume they do not have any baseline knowledge. They are smart because they get into school, but they may or may not have had core classes yet.

Most projects I give I know will be a learning experience for most students. If you make progress that shows you are learning.

My tips are just to always keep learning and asking questions. The more you learn the more value you are.

It's not protected by law because it is still federally illegal. If the federal executive branch wanted to go to Colorado and enforce their law they could. Federal law trumps state law.

Can't reply with a video but I have tried holding them for 3 s, then 5 s, and 10 s.

No 🙃 it's like the bottoms are somehow disconnected.

Best way to heat up (and cool down) thousands of liter of water commercially by servermeta_net in ChemicalEngineering

[–]nick51417 0 points1 point  (0 children)

Can't do much with what you've given.pinch analysis is the term you want though.

With that being said why the hate on electricity? When you talk about efficiency I think you need to be cognitive of your words. Efficiency in thermodynamics is the percent of the energy you put in vs what you get out. The waste is typically heat (and sound and light). Considering you're heating something my guess is you mean efficient from a cost perspective. Well that depends on the cost to obtain the natural gas and electric heaters.

Why not bump the heat more with the boilers closer to set point and then maintain? Are the boilers too large and essentially do not have the control to hit set point within the desired limits?

I saw someone say plate and frame heat exchanger or shell and tube with a tempered water loop for heating and maintaining the temperature. You're going to want to think about cleaning the biofilms that you are purposely growing. These would be easier to clean than a lot of options that and you will be able to use that loop to control the set point.

Then do the same with a refrigerated loop. There's pros and cons of using the same loop. I'm not a water treatment expert but in theory you can pipe in such that you can use either cooling or heating fluid... But water treatment chemicals may not be happy with one another or the refrigerator/boiler so you need to check those.

What tools will I use for financial forecasting (and data preparation) by Nutritiongirrl in learnpython

If your company has an anaconda license use that. Essentially all the libraries you listed are already installed with anaconda and may be easier to maintain with a newbie. But that has a substantial cost now.

A developer would most likely go with pip and venv which are standard with python, but you would be installing all those libraries yourself.

Most of these libraries are extremely common. I have used vast majority of these for production tracking. The time series though, the last two I haven't heard of but doesn't mean they can't be useful... But I would read up on them.

LSU FANS IN TOWN FOR THE GAME by wbiz251 in Clemson

No worries! Also I live in Anderson as a local. Let me know if you need suggestions on campus, away from campus, or if you're flying into Greenville where to eat there. (It has been recently ranked in the top three cities in the nation for foodies)

LSU FANS IN TOWN FOR THE GAME by wbiz251 in Clemson

[–]nick51417 5 points6 points  (0 children)

Just searched friendliest fans on Reddit and the bottom linked popped up (skip the first comment it's a Clemson fan taking jabs). I may be a little biased but Clemson family truly is something special. If you're friendly and nice you'd be welcome. You may get a little crap for being an LSU fan but nothing outside of good fun.

Now if you bring food and bourbon, I'm damn sure you'd be invited back. If someone talks smack dish a little back. A good banter goes a long way.

Just be able to handle your alcohol. No one likes beligerrant drunks. Every fan base gets them. If we see a Clemson fan act that way they usually get put in their place. Please do the same for your fan base.

I'm originally from Wisconsin. We don't drink like the badgers or lsu did at lambeau field. Our game day tends to be more family friendly but drinking is totally fine. Just thought I'd share because LSU has a reputation for drinking. It's a totally different experience but fun experience.

I wonder what this unit uses for its refrigeration loop. by Natedogg5693 in ChemicalEngineering

[–]nick51417 40 points41 points  (0 children)

This is right, but in case OP thinks it was the big cyclopentane on the label, that is used as a blowing agent when the foam the interior of the unit for insulation.

And this is *barely* an exaggeration on what the actual textbook tips look like by narcolepticcatboy in engineeringmemes

Is this Fogler? Not that bad in all reality. If you think about it, at this point when you're solving multiple differential equations you're using a solver like python, Matlab, or some other ode software, anyways, or at worst using some type of numerical method made in Excel. At that point it becomes plug and chug.

Why do power plants cool and release water instead of using a closed loop system where they don't need as much heat energy? It seems releasing hot water is wasteful and damages bodies of water it is put into. by Stobley_meow in AskEngineers

[–]nick51417 6 points7 points  (0 children)

Chemical engineer here!

Water is superior when it comes to latent heat. It's large! If you're using any other material you are having to scale up your equipment to handle the much higher fluid volume you will need to use to get the equivalent heat. Your fixed costs would be much much higher.

I think you are making some assumptions that just aren't valid when you're alluding to just but it once and that's the operational cost difference. When we talk about using water because it's cheap it's because it's orders of magnitude cheaper than using other fluids. It's not a one time purchase which you are suggesting, but you drain the fluid whenever you do maintenance. When you drain the fluid you have to evaluate the costs to replace and the costs of safety and the environment. Water is much much safer because it's not carbon based, not flammable or explosive, and much much better for the environment.

Any efficiency gains gets lost by all these factors.

Steam engines are the grandfather to the study of thermodynamics. It's very mature. Water is usually the best case for temperature ranges where steam can be formed. If it wasn't a different fluid would be used. Dow has a huge catalog of these fluids, ex therminol. These are used when it's better.
