Friction Factor for Wetted Wall Columns

AI Thread Summary
The discussion revolves around calculating the friction factor for a dilute SO2-air gas mixture in a wetted wall column. The user seeks clarification on whether the presence of a wetted wall necessitates different formulas compared to a standard steel pipe. There is also a question regarding the gas velocity at the interface with the fluid in the wetted wall column, comparing it to conditions in a dry cylinder. Understanding these factors is crucial for accurate calculations in this specific setup. The inquiry highlights the complexities of fluid dynamics in wetted wall columns versus traditional piping systems.

Hi!

I encountered this problem that asked for the friction factor of a very dilute SO2-air gas mixture in a wetted wall column. All the necessary information were given to compute for the Reynold's number. What I want to know is does having a wetted wall make it a different case (ergo use different set of formulas) compared to flowing in a typical steel pipe?

Thanks a lot!

Is the gas velocity zero at the interface with the fluid in the wetted wall column (as it is in a dry cylinder)?

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
