AI is the future for a lot of industries indeed!

Thank you for your kind words, it is much appreciated!

Thank you for your kind words and best of luck for your interviews!

Amazing! Thanks for watching & commenting!

Thanks for watching!

It all depends on that pump power 😂! Who knows that might be an interesting final-year project to design!

Thank you for your very kind words! Congratulations on passing your exam, wishing you every success in the future!

Thank you for your kind words!

The Heat of Reaction units needs to remain consistent within the numerator and denominator i.e. kJ/kmol, as there would be an inconsistent difference of a factor of 1000. We could express either as J/mol or kJ/kmol. I hope this helps, and thanks for watching!

Thank you for your very kind words! I am delighted our content has helped direct your path for your future career. If you need any further information/support please do not hesitate to reach out to me.

Thank you for your kind words, I am glad this helped with your project, wishing you all the best! Thanks for watching!

Thank you for your very kind words; it's greatly appreciated! I wish you every success in your studies!

No, the temperatures at each side of the conducting material are different due to the thermal resistance of the material and initiate temperature values. The term steady-state, in this case, means that the rate of heat loss is constant throughout the material, which is of course a fictitious statement, but it helps to simplify the modelling equations. I hope this helps, thanks for watching!

@TheChemEngStudent Thanks a ton!

Certainly, we can look at getting a video on that particular topic made for you! Thank you for your suggestion!

One of the best sources is Perry's Chemical Engineering Handbook. Alternatively, there are several online libraries which contain these values for a selected number of fluids.

@@TheChemEngStudent really appreciate your respond, Is it included with some food fluid, such as wheat dough, or not?

You are most welcome, thank you for watching!

This was my own data as part of my project. Most of the data can be found from databases; or are made as assumptions for the initial design. Thanks for watching, I hope this helps!

Thank you for your kind words, much appreciated! I can certainly look at creating more tutorials on those topics. We have some on Ideal and Non-Isothermal CSTRs already: kzbin.info/www/bejne/kJS7k56Ji9ikY7s

Yes, F is a molar flowrate. In the case of the example, it is the space velocity which is F/V which would give L/s. I hope that makes sense, and thank you for watching.

Yes, the optimal diameter is in mm. The reason for this is the set correlation that is used is raised to the power -0.37 for density and 0.52 for G (I'm not a mathematician, so not completely sure about the proof of the correlation), but from the reference this yields an optimal diameter in mm. Thank you for highlighting this and for watching, it is much appreciated!

The flow rate can be represented in either format, this is really dependent upon the information available to you. However, if we are talking primarily on the reactor input and output, they should be in moles, since those are the units we must use when modelling reactors. I hope this helps, thanks for watching!

Yes, you are correct, I misspoke in my explanation, thank you for highlighting that, it is much appreciated! The values represented within the table are obtained using the same method within the example, using the Erbar-Maddox correlation & graph.

Thank you for your kind words, it is greatly appreciated!

Yes, a cylinder can be generated through a similar means using the 3D shapes; we can look at producing a video tutorial on this for sure.

Yes, you are right, that was my mistake, thank you for noticing it and letting me know. I hope the overall idea still made sense. Thank you for your kind words and for watching!

Yes, the bubble column is a closed system, as are most bioreactors due to the cultivation duration. The schematics are just basic however, in more detailed ones you would find small relief vents, usually at the top to allow the air to escape, preventing an increase in pressure within the vessel. I hope this clears things up, and thanks for watching!

Yes, you are correct, some of the algebraic manipulations could have been done earlier; however, often, I find simplifying steps too quickly can be confusing for students who are just learning, but you are definitely right it could be done earlier! Thank you for watching it's much appreciated!

​@@TheChemEngStudent I recently retired from 21 years of higher education physics teaching and research. Although the research is theoretical and is continuing just as before... My PhD is in EEE, but I now find myself learning Chemical Engineering as part of the diverse skillset required for my new career managing employees who design heat exchangers and reactors. You videos have been far more helpful than the textbooks!

@@stevenverrall4527 Thank you for your very kind words, it is greatly appreciated! I am truly honoured that a distinguished highly experienced academic is finding value in my work. Full respect for learning Chemical Engineering, one of my specialisms is in Heat Transfer and heat exchanger design and optimisation. If you have any particular topic requests please just let me know and I can create a video.

This really depends on your background and what elements you find most difficult. I would say either taking additional mathematics courses/classes at university or seeking some tuition services. If you would like to get in touch with me, I can look at scheduling some support sessions as I also offer mentorship to some students if this would be of interest to you?

Thank you very much for your kind words and for subscribing, it is greatly appreciated! I'm glad you find the channel helpful, and if you ever need any additional information/advice, please don't hesitate to reach out!

Thank you for your kind words, its much appreciated! I understand your question as at the time I had the same one. This pressure drop as it is on a per meter basis is telling us the pressure/force the pump will push the fluid forward by every meter (the pump head would tell us how many meters this would be valid for). This relationship allows us to specify a distance to model around giving us the pressure drop from point 1 to point 2. There are lots of other correlations, this was the one I used in my design based on the information I had. I hope this helps and thanks for watching!

We can express this as kg/kmol which allows us to keep the same value since the conversion from g to kg would cancel the conversion of mol to kmol. I hope this helps, thanks for watching!

The value of 104 is the heat loss provided in the question description. The 4.2 is the conversion from kcal to kj and the 1/3600 is the conversion of hours to seconds. Thanks for watching and I hope this helps!

I have a Scottish accent

@@TheChemEngStudent yup i thought so, cuz its definitely not american nor aussie. and accentts like canadian, south african and new zealander tend to be clear and not too distinct like welsh, scottish and irish!

@@9LimaAlpha7 It is a distinct accent, to be more specific I have an Edinburgh Scottish accent. I hope it isn't too difficult to understand!

@@TheChemEngStudent no not at all, in fact its quite charming! i have lived in england for a few years and ive aquired a british accent (not as a native, but very fluent) hence, i dont struggle to understand different accents

We can certainly look at putting something together, great recommendation! You are definatley on to something, once you understand physics you have a different perspective on the world, and this would certainly benefit everyones pockets!

Thank you for your kind words Sir! Much appreciated!

We can make this assumption when we consider the overall balance that is to say that both n2 and n4 can be grouped to represent the "top product" leaving the entire system. This is only applicable for the overall, this wouldn't apply to the individual unit operations balance. I hope that makes sense and thank you for watching!

Thank you for watching, yes you are correct in that there is essentially a quasi-state occurring where the value would tend towards zero, however for ease of explanation for these tutorials we don't want to over confuse as in my experience as a lecturer, as soon as you enter the realm of quasi-systems all is lost. But you are absolutely correct and thank you very much for commenting on this!

As it is Non-Newtonian you need to identify a suitable model that you can extract the reliable physical properties from. Then we need to know the flow regime using Reynolds, identify the suitable shear stress formula. One to potentially use is... gamma = (4.Q/pi.r^3). The actual equations however will vary depending on the model used i.e. Bingham, Herschel-Bulkley, Cross, etc. I hope this helps, and thanks for watching!

@@TheChemEngStudent Any book reference that you recommend related to this subject ? Thank you

@@josegabrielhernandezaguirr5267 There are a lot of great books on this, I have attached a copy of our course descriptor which gives you a list of the books used for making this content. I hope this helps. If you need anything else please just get in touch! www.chemengstudent.com/wp-content/uploads/2024/06/Fluid-Dynamics-Mechanics-Course-Descriptor.pdf

We are currently updating the library and hope to have it fully up and running in the coming months. I will comment the link when its ready!

@@TheChemEngStudent thank you !

That's a really interesting question! The key linkage here is in the use of Grashof number as the Rayleigh number is equal to multiplication of Prandtl and Grashof. Prandtl explains the thermal diffusivity whereas Grashof explains the buoyancy and viscosity. These combined can then be approximated to Nusselt number which explains the heat transfer effects. There are numerous correlations based on flow type, and geometric confinement. I hope this helps, thank you for watching!

Thank you for your kind words, much appreciated!
