Does particle density affect the displacement coefficient? Would a 1 nm tungsten carbide particle have a lower displacement coefficient than a PVC particle?

good stuff

Thank you, you are the only guy on youtube who done video on this.

Hello Sir

Informative

excellent presentation

Thank you and im watching the video for the second time and now it make sense.😊

Thank you.

Great video, thankyou for sharing. It was very helpful for my final year project.

Would you plz share the band charts

Thank you that was so helpful

Check out our video - czcams.com/video/vVqRBHQ2U2M/video.html

Thank you for this 🙏🏾

We'll need to start including "confirmation" into this framework. I like the term "validation" better, but it appears that the professionals' consensus is "confirmation."

this is very detail thx

This is very helpful thank you

Thank you so much for this video, it really helped me

고마워요!

Thanks for the informative video.. When we enterface beetween ventalation and fire alarm system,should exhaust stop when detect smoke,?or Exhzt energize if smoke is detected ?many thanks ..

This is super useful information. Thank you for sharing

Thanks for the great video

Very interesting. I am at present being investigated for resperatory problems.

Hi, this was fantastic. ACGIH is not a consensus group, and TLVs and BEIs are not consensus standards.

what is the source of information given at 17:58?

Sir please can u help me with my assignment 😭

Thanks

Oouu ok2...tq for information

Thank u da boy

Thanks for this update. I did a dust extraction using a Centrifugal fan but the fan pressure was too low to absorb the powder dust. can I use an Inline fan to enhance the system performance? kindly reply me

As a health scientists your claiming it occurred naturally? Is your funding that strict with oversight?

Nicely Explained...

Very much useful n need to learn

Looks great!!

Good video. I build these systems for a living for >25 years. Sometimes more than 100 hoods per system. Then there is the scrubbers and dust collectors. And the chimneys.

Thanks for the good education material. I am studying Safety & IH in Korea.

Thank you🙏

Great Explanation Sir !

i did not understand why you chose 84th percentile for calculating the geometric standard deviation using the log-probability plot, could you please elaborate on that .

Great video thank you.

Hello sir, I am having airborne dust concentrations data as PM10, PM2.5, PM 1 . These data was taken before and during dust producing work in a field study. N=5 How can i compare these before and during operations data ? It seems that there is percent variation in dust concentrations in atmosphere between before and during operation data based on particle size. Before operation: PM 10 ( particle size less than 10 microns) is sharing 40% of total airborne dust, and PM 2.5 ( particle size less than 2. 5 micron) shares 10% of total airborne dust. During machine operation: PM 10 shares 60% and PM 2.5 10% only. It seems that PM 10 share is increased due to that machine operation? Which test is suitable for analysing these type similar data for discussion ? How to use statistics? Any comparison among these particle sizes? thank u.

Do you have any idea why your mass concentrations in the different sizes looks so similar?

Can a fate and transport model of nanoparticles using a CFD software could be drawn?
