I am searching for a database of flue gas scrubber design parameters. Such as, common reagents to use for certain VOC compounds, L/G minimums, and Absorption Factors. I do not have access to programs that can model this data for me. If anyone knows of such a database and is willing to share it...
I have found resources that explain the impact of a 95 deg elbow at the inlet and outlet of a centrifugal fan, but nothing else. I know a sloped inlet and/or a sloped outlet duct would cause a non-uniform velocity profile, which would cause performance losses. But I am hoping there is a way to...
I created this post to help me better understand how to deal with pressure drop in parallel. Can you explain to me why I need to define a fictitious flow for this fictitious and extremely simplified example scenario?
You are right! But I knew this. Granted, my understanding of the relationship between flow and pressure could easily be used as an example of the Dunning-Kruger effect. I just find it easier to understand if I think of the suction as something consumed by the pressure drop. I know it is not...
Embarrassingly, after rereading your post for about 30 minutes, I finally got it. The way I now like to think about it is in terms of inlet and outlet pressures. The outlet pressure of both units 1 and 2 is created by the suction of the fan. This suction pressure exists in line 3 and therefore...
Assume any flow you want. What I want to know is does the fan need to be sized for 7"wc or 14"wc static pressure. This is ignoring that fact that I would need to know desired suction pressure at the inlet of unit 1 and 2, and the desired outlet pressure of the fan.
I am a chemical engineer working on a spreadsheet that calculates heat capacity using the Joback method (see links below if you need more information on the Joback method). For this calculator, I am creating a database of chemical compounds and their functional groups, but it is taking too long...
Imagine you have two ducts (ducts 1 and 2) that merge into a single duct (duct 3). There is a fan located on duct 3 that needs to pull air through ducts 1, 2, and 3, and then exhaust it through duct 4. Both ducts 1 and 2 have obstructions that cause a pressure drop of 7 inches of water column...
You're probably right about me not knowing what I don't know, and I should have clarified more. I am not fully left to my own devices, as my supervisor is always there to answer any questions I have and look over my work. However, I want to be able to do some learning on my own time, so I was...
I am a chemical engineer fresh out of college and have landed myself a job as a project engineer. Part of my job is spec-ing and ordering electrical parts like actuators, VFDs, proximity switches (pressure and level switches too), etc. I lack a lot of the basic knowledge when it comes to...
