I can't TELL you the number of times, over the course of my life, that I have heard people attempt to explain the dewpoint. And yet was not until seeing yours that I *finally* understood. Excellent graphic representations of the concepts. So grateful to you…thank you!
you have no idea how much you have saved me with this video! no video or article could help me understand relative humidity, it was all confusing and contradictory. so thank you sooo much for this!!
Wow this video was awesome. I was having trouble grasping the concepts of RH and DPT fully. I read the textbooks and powerpoints but was struggling. However, with this animation, it just connected all the dots. Thank you and I really hope ya'll can make more of these videos.
This is the best video for understanding the relative humidity concept coz i watched lot of video in you tube related to RH but nothing helps to understand the concept clearly but this animation is simple and effective to understand the RH concept easily.. Good work and thanks for the very useful video..
There are many people out there to change the temperature-relative humidity shit. However, this video was the dehumidifier needed for moisture reduction a bit...Now I am feeling cool... Thank you 🤗
well understand in less than 4 mintues with this temperture-moisture-R.H. chart and the new term "dew point temperture of water = fully saturated air with water" Never come across with the chat and term at physic lesson (perhaps sleep at class when I was young). Very useful information when learn how air conditioner and dehumifier working at DIY hobby class. Thank you.
Thanks allot This is the best video I have ever seen, I guess I know and have much better concept understanding humidity and how it relates to moisture and dew point... I will be great full if you can do video on how cooling of evaporative air cooler get effected when these factors are changing, I have practically experienced at dry air e.g 13% the higher the temperature better the cooling, only thing I forgot to monitor was dew point which I believe must be very low after watching this video, we had 13% humidity and 41c temp and I was able to get 24c room temp with pleasant feeling, on the other hand when we had 45% humidity and 35temp, I was hardly getting 28c temp in the room and feeling suffocated ... It was really so confusing but I guess I have much better understanding about what is actually happening,.. will be great if you can have video in this topic as well
Unfortunately this picture is very much missleading. Take a sealed box half full of water, the other half is vacuum. What happens? The system will equilibrate into a state where a specific mount of water vapor is created. It’s vacuum and in your picture that would not be possible if air “holds” water….
I am also interested in the chart that shows the relationship between temperature, moisture content and relative humidity. Where I can find this chart. Thanks
Thank you very much for the amazing explanation. I have 2 questions. 1) If the temperature in a city increases, will the dew point temperature also increase? 2) Assume that the actual air temperature in New York city and Washington be 30 C and 25 C respectively. Let us also assume that the dew point temperature in both the cities is 22 C. Where will the person feel more humid?
+Satish Natarajan 1. The dew point temperature is dependent on moisture content. Increasing the ambient temperature will not increase the dew point temp unless the moisture content also increases. 2. Depends on the moisture content.
Okay, so why do lower dew points feel more comfortable? If no more water can be evaporated, such as sweat, and at 100% relative humidity, then why can't I just look to see if there is 100% humidity? It doesn't matter what the temperature is. If it is saturated then it is saturated. How would I be able to evaporate sweat better at lower dew points, when all that tells me is the temperature at which the relative humidity reaches 100%, or saturated? 100% relative humidity also tells me that.
DUDE IKR??? This song goes SO hard bro!!! Freddie Mercury, Beethoven, Elvis, Micheal Jackson, Drake and so many more THWART IN COMPARISON TO THIS BEAUTY!
So, you say there's 15 grams water vapor at 100% humidity at 20C. In what? In a liter of air? In a cubic meter? In your living room? In the sky above New York? The cute little volume bubbles expand and shrink, the temperature changes and the grams go up and down, but you never explain what these numbers relate to in precise engineering terms. Maybe you should clarify this for yourself, before you try to "teach" it to others.
