Dear all,
Please find attached an Excel file which will be used to calculate agitator heat transfer coefficient. I hope it will be useful for you.

best regards

that is grate of you ,

In fact i being a production person in pharmaceutical industry was looking for these type of files in the forum

any thing related to reactor .

can you please provide some more with respect to utility load calculations & agitator selection / scale up

that will be great of you .

I like this too. If you'd consider cleaning up the units of measurement a little (pick either Imperial or Metric and use throughout), and submit for inclusion in the Download section.....we'll get your membership upgraded to ChE Plus.

Thanks for your post with file in .xls form. It's useful to me. However, do you have another sheet (like agitator.xls) which helps to calculate a agitator for mixing 2 liquids? I need to calculate a agitator which mixes 2 liquids (different in viscosity and density) in a reaction process.
I hope you can help me in this matter.

Thanks in advance

This is a great contribution on your part. My suggestions for this workbook, prior to submittal, are:

• Format the Introduction and Heat Transfer worksheets’ layouts so that the print out can be read with ease in one or two pages without breaking up of the information.
• Fully identify the reference given as Chemical Process Equipment Selection and Design. Is this a book? Who is the publisher? The edition, year, author, and other identifying data.
• Identify the Input Data cells on the Heat Transfer worksheet by coloring them in Yellow or other color. You can also tag them with a comment.
• Please identify all the UNITS for the variables given. You use both English and SI units; that’s OK. But you leave the units of Ti and Tf blank.
• The Data worksheet is blanked and protected. Is this worksheet required? If so, why blank it? What does it contain?
• In the application of both an internal coil AND an external jacket, what does the calculated “U” represent? How is it calculated?

Thank you for this contribution.

Thank you Art for your suggestion,

I protect sheet to prevent changing data and only Input Data cells are unprotected and should be filled. This workbook can be improved to calculate other parameters such as adding reaction heat and sizing proper coil or jacket, calculate scale-up parameters and also heat transfer for both coil and jacket , that you mentioned. I hope in future I can improve it.
I corrected workbook based on your suggestion, and substituted it with previous one. The password is 123

Yes, please continue the development of this spreadsheet and submit it to me through the support system when it's complete.
