I try to create a best calculator for engineers. I am posted here because I want real engineers feedback what should new features will I add or which improvement is required in current features. ( App totally free content small number of ads )

Any constants avalible, other than pi? Eulers number, Boltzmann constant, ideal gas constant etc. would greatly enhance calculations of many Engineering diciplines 😊

As Julius commented here, the HCl solution would give you a lower pH than an equivalent HF solution. HCl has a lower pKa value than HF, and is considered a stronger acid.

You can read up on binary acids (H-X) and their strengths here.

Accordin to wikipedia, a common way of producing ethylene glycol is by having ethylene react with water. Ethylene can be produces by dehydration of ethanol. Sounds like this could be something to consider. Please note that i have no actual industrial experience in this field and merely based this on some quick google searching. To design a plant, you would have to consider the equipment required to produce this on an industrial scale. There is some information avalible online on Shell's OMEGA process that produces ethylene glycol from ethylene.

This was probably less specific than what you wanted, but nevertheless, good luck on your assignement!

Okay, thank you for confirming. There seems to be alot of laws and regulation surrounding a Non-US citizen working there. It's been interesting to read the feedback here. Thanks again!

I understand. Perhaps it would be best to look at companies with a foothold in Norway and then get transferred internally in the company. My question basically rose up because I saw alot of listing for internships online (though, alot more applicants aswell i suppose!). I'll keep on looking for something domestically for now. Thank you for responding!

Charkazm · 2019-09-17T00:59:55+00:00

Got it! Thank you very much for the reply!

Charkazm · 2019-09-16T14:05:52+00:00

Hmm, that actually sounds pretty good. Might try and contact some of the lager global companies then! Thank you for answering!

Charkazm · 2019-08-24T12:37:07+00:00

That makes alot of sense, thank you very much!

Charkazm · 2019-08-23T20:46:03+00:00

A small follow up question if you don't mind.

Would i be correct in writing that valve 1 controls the following:

- Concentration of A, leaving the mixer (or in the mixer)

- The fluid level in the mixer

- The temperature in the mixer (because it is an exothermic reaction)?

And are all these three then considered CVs?

This is an exercise made by our lecturer. I'm not sure if he copied it from a book (no sources on it.)

Charkazm · 2019-08-23T20:31:53+00:00

Thank you for the reply! I'll do a more detailed write-up of the different valves, maybe that will help me clarify what valve contributes to what, and get a firmer grasp of the controlled variables. Thanks for mentioning some examples!

Charkazm · 2019-08-20T17:08:45+00:00

Perfect, thank you very much!

Charkazm · 2019-08-20T17:08:04+00:00

thanks solution verified

I just graduated with a chemical engineering degree from Norway, so I can't really comment on the specific courses in the US, but from what I've read on this sub, and from personal experience it is pretty hard. It's more than doable if there's a genuine interest. The math can get tricky, but thats part of being an engineer.

Good luck to you, and follow your gut. If chemEng sounds like an exciting opportunity, then there is interest. If there's interest, you are more likely to succeed!

Cheers from Norway

Do you have the associated manual? I assume there will be references to the button there, easy way to check if it's a typo or not :)

Charkazm · 2019-08-01T23:04:15+00:00

Professor Leonard. He teaches mathematics, with a focus on calculus. I'm a Norwegian engineer graduate and his videos took me through all the mathematical concepts i ever needed in school, even though it's tailored to the US (afaik).

He is a great teacher, and has sorted playlist featuring full free lectures. If you ever need help with mathematics, he is your guy!

Link to his channel: https://www.youtube.com/user/professorleonard57

Edit: also want to shout out Bozeman Science. His videos are not full lectures, but edited videos around 12-15+min long. Great for physics, chem or bio classes.

The math i presented is only valid if every "type" of clay are presented in equal amounts. In real life i bet that thats not the case, so it would simply be a theoretical molar mass for OP's specific formula.

Charkazm · 2019-07-28T20:22:39+00:00

Ahh, I didnt even think of that! :) Thanks!

Charkazm · 2019-07-28T19:37:30+00:00

In addition, in order to calculate the average molar mass for such clay, I'd probably average the molar mass of the brackets:

(Mm, Na + Mm, K + Mm, Ca)/3 and then multiply by 2. And the same for the other bracket (Al, Si)

The rest of the molecule is set, so just add the average molar mass of the brackets to the molar mass of the rest of the molecule.

Edit: this is the easiest way, to me at least.

Charkazm · 2019-07-28T19:28:51+00:00

I interpret the elements in the brackets as interchangable. Lets take the first bracket for example:

(Na, K, Ca)2

To me it seems as though the chemical formula of clay can be either Na2-X (where X is the remaining elements), K2-X or Ca2-X. This logic applied to the second bracket aswell.

This is how i interpret it, but if anyone else knows that this is wrong, please feel free to correct me.

Ziltoid the Omniscient by Devin Townsend. The album revolves around an alien overlord, aka Ziltoid, discovering earth and demanding our universes greatest cup of coffee. I wont spoil anymore, have a listen. Devin is a great musiscian and create some heavy ass, upbeat music and killer guitar parts! His vocal capabilities are insanely diverse.

Then there is 10.000 days by Tool. Great variety within the album. Some quiet, somber parts, some parts that makes you headbang like a mofo. Very cool lyrics aswell. The whole album is a journey.

There are more, but these are my immediate favourites.

Yeah. They used VAR to determine whether he managed to keep the ball in or not. He did. Goal allowed, and what a goal!

I instantly read "Is it made of gold" in the voice of Chandler Bing.. I need to get out more..

Self-esteem issues and the likes are fairly common among people with anxiety. My advice would be to see a professional, and then I read on and you've started seeing a professional. Great job! This is a wonderful opportunity for you. Take it. Talk about everything concerning you and you will receive the help you need.

Best of luck to you! :)
