Anyone know how to design a kettle reboiler for a plant?

 

I've tried various sources and references, just can't do it alone.

 

Any chemical engineers here? or other chemical engineering majors?

 

help.

 

I need to graduate.

 

PM to help me graduate.

 

I think this might be the most advanced material anyone has asked for on this thread LMAO rlytearpls.png

Hello, so basically I flopped a really bloody easy Q on surds 

 

It was in this format: RRmSmvw.png

Instead of only multiplying both top and bottom by only root 5 when rationalising, I multiplied by (3 x root 5)

 

Would that make the final answer wrong? Given that I've simplified?

3sqrt(5)/3sqrt(5) is still 1, so multiplying that fraction by it shouldn't change your answer. The 3 will divide out anyway.

It wouldn't have been a big deal since it's still a 1:1 ratio.

You got 6rad5 / 45 right? If you simplified you would have gotten the correct answer which is 2rad5 / 15

Was it a short answer question or multiple choice?

Oh okay, thank you! I was quite dead today so I can't remember if I simplified to the very end or even did the question right, but if that's the case I should've at least still gotten a mark, lmao. I really gotta get my shit together unimpressed.png

 

Ahaha, it was short answer and more complicated than just this, I can't remember the answer but it ended up as something minus something, all over something. 

 

Thanks again~
