Does the wet bulb temperature tend to be cooler than the dry bulb? If so, in what case would T(wet bulb) be greater than T(dry bulb)? Thanks for the video, it was an excellent explanation
@ClimatebyDesignInternational3 жыл бұрын
Vanessa: Good question. The wet bulb temperature will always be lower than the dry bulb temperature but will be identical to dry bulb when at 100% relative humidity (the air is at the saturation line, and you can check that out on our psychrometric chart and webinar). Hope this answers your question, if not let us know! Dr. Dry

I would like to thank you this webcast. For the last 25 years I have been teaching psychometrics to my employees and follow union members, information you have provided in this webcast has been spot on. I teach this information, and I'm ask why other psychrometric courses only teach how to plot things on the chart and not real-life applications. The biggest thing I liked about your course was when you mentioned that its in pounds dry air and how to convert it to CFM's

for 45% relative humidity @ 95 degrees I´m counting abt. 112 grains, not 140? for 140 grains @ 95 degrees I would say abt. 55% RH what am I not getting?
@ClimatebyDesignInternational3 жыл бұрын
You are correct that 45% RH at 95 degrees is 112 gr/lb. We apologize for the confusion.

So...,wet bulb thermometer gives you the amount of moisture in the air? Or you have to do some math to figure it out?
@ClimatebyDesignInternational4 жыл бұрын
Hi Adil, Wet Bulb will give you RELATIVE amount of moisture in the air. If you want to know the AMOUNT of water in air then you need a corresponding measurement like dry bulb temperature. With two points you can then find the ABSOLUTE measurement of moisture in air like grains of moisture per pound of dry air (or grams per kilogram). We have an application for that called DRY TOOLS.

The higher the difference between the two thermometers, the lower the amount of the moisture that’s present in the air. That’s my understanding.

Doctor, what does it infer to air if both the dry bulb and wet have the same reading?
@ClimatebyDesignInternational4 жыл бұрын
Hi Neil, That the air is saturated, or 100% Relative Humidity. - Dr. Dry
@TheMaverickanupam5 жыл бұрын
Thank you. But one question remains, as we are dipping the wick in water, why is it being used as a proxy for moisture in the air?
@ClimatebyDesignInternational4 жыл бұрын
Hi Anupam, When air being measured moves across the the wet bulb (the wetted wick) it will evaporatively cool the thermometer to 100% saturation, lowering the temperature reading on the wet bulb thermometer. - Dr. Dry

@ClimatebyDesignInternational4 жыл бұрын
Hi Frederick, Humidity sensors can come in all shapes and sizes. Most electronic sensors measure temperature and relative humidity and then electronically convert it to other outputs. That can include wet bulb. The sling psychrometer used in this video was used primarily to demonstrate the concept. - Dr. Dry
