Wet Bulb vs Dew Point Temperature

Wet bulb temperature and dew point temperature are different, but they sound sort of similar. How are they related to each other? We look at the air-water system to find out.

Process with Pat is the place to come for perspective and to ask stupid questions. I want you to leave more knowledgeable, confident, motivated, and most importantly, curious. I also want to invigorate a field that seems tired and uninspiring, at least if you get your perspective from internet forums. These are not lectures. This is a place for you to leave thinking “Oh! That’s why...”

This channel is not only for chemical engineers - anyone who works with processes should be able to find something of value here.

I cannot overstate how helpful the graph and animations are. There is simply no better to deeply understand how these variables relate to each other. Thank you for making this!

[shabareeshskumar]

The effort u hav put into making this video is amazing.. great explanation and perfect use of animation..good job Pat

[chloet]

This video and your video about dry vs wet temperature have been so valuable to my understanding of psychrometric terms. You addressed exactly the questions I had, especially the WHY. Thanks so much, keep posting!

[willfindjr]

Hands down the best video explaining the Psychrometric chart. Great job!

[bssat]

You using the psychometric chart really helped in the understanding of wbt, dbt and dew point. Thanks!

[HassanAlhassan-gbxg]

I don't usually comment on Youtube videos, but I have to say this was impressive.

[ChemEngWeekly]

Great explanation once again Pat! They really do sound like the same thing, but this helps clarify the difference very well 👍

I have a doubt. @7:00 when moisture in cotton is taking heat from surrounding air then how does temp of thermometer decrease? the cotton should primarily take heat from thermometer's bulb. right?

[wasathnaotunna]

what a nice explanation. this is the first time i understood this chart. Thank you

[esanariam]

I took a three days course for Water Damage Restoration Tech, didn't get it but you explained within 10 minutes 🙏🙏, Thank you so much!!

[Shubhambdhage]

I think this video is one of the best video so far I have. Thank you for making video

[Cottonstemfarm]

One of the best examples I’ve found so far thanks.

[rajdipak]

Great explanation. I am quite new in this and just trying to learn especially for HVAC system. Thank a lot.

This chart really puts in perspective how extreme the dreaded "wet bulb events" really are. To have a wet bulb temperature above 35 degrees you have to be in the very top corner of the chart (or maybe more likely a bit further to the left and out the top at extreme humidity). Dryish air even at death valley temperatures are really not all that bad in terms of wet bulb temperature. As long as you have water you'll be fine. Evaporative cooling is really effektive when at high temperatures. You need the high humidity for it to be truly dangerous.

Extremely well explained video. Thank you so much.

[cheeseman]

I've been studying for the FE and this was a great explanation

[pavithraa]

Good explanation and easy to understand..And wet bulb temp is used in cooling tower and dew point for compressed air system..please do video on this.

[panda]

Top videos champ! The live graph helps immensely, you speak well and are thorough in explanation and make it easy for our brains to process.

[shridharpandey]

Very cleary explained....shows good knowledge

[RohitKumar-ycvg]

Thank you very much for this great explaination
