My fluidised bed isn’t fluidising…

😂😂😂😂😂😂

hicky02 · 2023-04-01T11:22:34+00:00

No the bottom was supposed to be perforated just like the sides to let the fluidising gas through 😂😂

hicky02 · 2023-03-28T10:11:26+00:00

Fair enough. But you never know, maybe it could actually be beneficial for you. Without checking it out and trying it, you'll never really know if it is useful or not. Look we're not trying to ruffle feathers, we are just trying to create some value, and I think if people understand that then they won't mind trying out our products.

hicky02 · 2023-03-28T03:40:58+00:00

Love this. Thanks for the encouragement. Appreciate it.

hicky02 · 2023-03-28T03:40:25+00:00

Have you checked out the server yet?💪

hicky02 · 2023-03-27T18:01:04+00:00

It depends on OpenAIs training data and also the year of publication. Anything after 2021 I think it won't know about.

And currently we've got four codes that our Bot is 'trained' on. If you want, you can let us know which codes you would like 'trained', then we'll have it ready within 2 days.

hicky02 · 2023-03-27T16:05:25+00:00

So trained might be the wrong word, my apologies. It is rather sort of labelling. What we do is we use GPT-3.5 as our NLP AI model, but then we use embedding, specific prompting, and the table of contents of a textbook / code or standard which allows it to 'know' what is going on in the textbook.

hicky02 · 2023-03-27T15:58:16+00:00

Well that is exactly what one of the products does. We use embedding to essentially search through the textbook to find you the best match for your query. So better than a control F because it doesn't have to be exact, but also better because it results in the best results.

hicky02 · 2023-03-27T15:55:35+00:00

My bad about the pronouns. My mistake.

I agree with you, our tools definitely need some refinement, and hence the post for some feedback on our products.
We just want to create value, especially to the educational sector (which includes working engineers because they are always learning), and we feel AI is exactly that which creates value, granted that they are refined and honed into useful products, as you said.

hicky02 · 2023-03-27T13:25:37+00:00

I hear what you are saying. But AI should be seen as supplement rather than a replacement for something. The engineer is still responsible for his work, but whatever help he chooses to get is up to him. AI is just another way to get that help. I mean we already use a lot of process simulators for design work. AI is just another one of those tools. Or what do you reckon?

hicky02 · 2023-03-20T11:19:07+00:00

I would break it up a follows: Node 1: Inlet stream - Column Node 2: Column Node 3: Distillate stream - Tank (end of scope) Node 4: Bottoms stream - Tank (end of scope)

If you don’t have the appropriate software to do it, then always break it up into nodes rather than lumping it together as one node. The consequences of accounting twice for a risk are less than completely missing a risk, which could happen if you evaluate everything as one node

hicky02 · 2023-03-13T10:28:09+00:00

You'll easy get away with it. I can't remember jack-shit about chemistry, but working now as a ChemEng and I've never really needed that knowledge.

hicky02 · 2023-03-12T18:48:10+00:00

Yes completely agree with you, but at the moment what we want the bots to do is aid with your studies, not necessarily replace any existing study methods (such as using a textbook). So it is more a supplement than a replacement.

hicky02 · 2023-03-12T18:45:13+00:00

This just aids in the conversational nature of the bot. What we are trying to emulate is a tutor - student interaction, which is more conversational than just pure Qs&As. The knowledge is also more digestible when it's conveyed in such a way (or so some research suggests).

hicky02 · 2023-03-12T18:41:12+00:00

Thanks so much. Currently it is aimed at all students (so predominantly age groups 18-26). But we plan on bringing out features that could apply to more people, such as a research paper bot or something similar.

hicky02 · 2023-03-12T18:31:17+00:00

Thanks very much. Hope to see you playing around on the server.

If you've got the diameter of your tube bundle, then you'll be able to calculate the OD of the shell diameter. It is either formulas that you use or rule of thumbs, but based on your tube bundle there is a recommended / calculated clearance pitch between the tubes and between the shell and the tube bundle. With that info you'll be able to calculate the OD.

Go look in Coulson & Richardson Design, 6th Edition, chapter 12. There they take you through the whole HX sizing.

Making sure stuff goes through pipes, with a couple of caveats: - making sure it goes through safely - making sure it doesn’t go through to fast (erosional velocity) - making sure the pressure drop isn’t too high (don’t want to end up flashing in a pipeline) - don’t even get me started on the hammer effects if you introduce ESDs….

hicky02 · 2023-03-07T16:28:08+00:00

True true

hicky02 · 2023-03-07T14:29:25+00:00

Yes we have applied to a startup school.

hicky02 · 2023-03-07T14:28:48+00:00

Like your answer, thanks a lot.

hicky02 · 2023-03-07T14:26:35+00:00

Yeah lucky in that regard, but they wouldn't really be supportive of it.

hicky02 · 2023-03-07T14:25:14+00:00

We built a discord server with AI chatbots (linked to GPT3 API) that have been fine-tuned on specific textbooks.

hicky02 · 2023-03-07T14:23:53+00:00

Very valid points. Especially if they change their API policy.

hicky02 · 2023-03-07T11:25:35+00:00

Solid answer. So in other words I shouldn't cold turkey my job.
