Hello,
I try to calculate pressure drop through rectangular ducting (sound baffle), which will be placed on air inlet. I'm new to this and need some guidance.
Screenshot for reference:
I found formula for calculatig equivalent hydralic diameter for rectangular shaped duct on Engineering...
Hello again,
I see now how this can be confusing. The last load (nr. 4) is due to the weight of the beam itself, so the last force should actually be drawnn as an equally distributed load.
This is a 3D-problem, which I similified to 2D. Perhaps oversimplified? The frame it's not exactly made...
Hi,
I need to find the optimal placement for antivibration mounts. In order to do that, the reaction forces have to be calculated first.
Here is a FBD of the structure:
What will be the resulting reaction forces at support A?
Hi,
I've been thinking about the solution for cleaning a water-cooled gas cooler and would love to hear some advice from the smarter people with more experience.
Description - I will try to roughly explain the concept.
Gas Cooler is used to decrease exhaust gas temperature. The exhaust gas...
Thanks Latexman and Jari!
Going further with this thought ... Caloooomi mentioned that
. What would be the duty for 270K SCFH? How can I calculate this? Would I need an engine with better performance?
Pierre, Walt - Thank You for the book, I've started to read it to get a better understanding of concepts within heat transfer. Great read so far!
Rputvin - Thank You for your throughout answer with explainations. I really appreciate it.
Hi Ed and thanks for the answer.
Tubes are in parallel.
Is there any way to determine critical in/out velocity?
What about the statements (1) and (2) I made above? Can You either confirm or deny?
Hello everyone, hope You all are staying safe in these challenging times.
I'm designing fin-tube heat exchanger (water-air). I have all the calculations needed, heat exchanger is manufactured & tested and works great, but as a curious person I'm still wondering about some theoretical aspects. I...
Thank You all for the answers, I appreciate every single one of them.
Additional question on the sidelines out of curiosity. What actually determines the SCFH value in this case? Is it Triplex Pump in combination with Vaporizer? In other words - If I wanted to design a system with higher...
Thanks for all the answers, I really appreciate this discussion and all of your tips.
I haven't been clear enough with explanations and I'm sorry for that.
No, this is planning phase, so everything is just theoretical. I need to provide minimum discharge temperature when at the highest rate...
I don't know suction temperature, but I guess it's below -196 degC as it's liquid nitrogen.
If You mean the one on the inlet side, it's a charge pump (centrifugal).

Hi LittleInch and thank You for the answer.
As You assumed correctly it's multi cylinder, triplex pump.
Simplified schematic (no valves, TI, PI) for LN2-GN2 line looks like this:
Since I have discharge pressure, flow and cylinder volume I can probably calculate temperature somehow. However...
Hi all,
I'm a fresh mechanical engineer with no others in my company, so I don't really have anyone to discuss stuff with. I don't have much experience with thermodynamics, so I would really appreciate all the help I can get. I have to provide the minimum discharge temperature when at the...
