Wet bulb temperature explained | Dry Bulb and Wet Bulb Temperature & its significance | Hindi

[@SandeepAcademy9]

Check out 10:18 Actually all molecules are in random motion with different velocities. Some are moving slower and some are moving faster. The average kinetic energy of all the molecules is called sensible heat and it is proportional to temperature. Only those molecules which is having very high kinetic energy will be able to break the intermolecular forces and will go into vapor phase. So the average kinetic energy of remaining molecules will go down and hence sensible heat and temperature of remaining molecules will drop. As temperature of water drop decreases with time, vapor pressure decreases causing a reduction in partial pressure driving force. Temperature driving force for heat transfer from ambient air to water increases.

This video contains some theoretical concepts which is very difficult to find anywhere. This concept help me with all the doubts of Cooling tower and humidification. Thank you sir.

[@SagarPathak-w4p]

What an extraordinary explanation..! U know, I am an Industrial Hygienist by profession. With the use of this concept, I have successfully correlated the concept of Body heat removal by our body & why & how it's affected in a highly humid atmosphere. Now I can utilize this knowledge to meaningfully educate the workers/employees throughout my professional life....! How many will be affected by this knowledge (in a positive manner, of course)..!! I appreciate the fever that u have done, rather you are still doing by this way...! Salute to the soul..!

Sir.. Adiabatic saturation and dew bulb temp ke relation pe ek video detail me bna dijiye plz..

[@jasvinderrana9546]

Very nice knowledge

[@pruthveshmandle4978]

I was reading the concept of adiabatic saturation. In this concept, it is written, that "The thermodynamic wet bulb temperature will be less than the entering air dry bulb temperature but greater than the dew point temperature" However, later I found a True/False question in which it was stated that "Wet Bulb temperature is always lower than dry bulb temperature but Higher than dew point temperature" I thought the answer to be True but correct answer was False. Can you explain why?

[@mhttwr]

If it is lower than dew point temperature than mass transfer from wick to air is not possible. Below dew point water will not create vapour pressure.

[@priyanshichoudhary7795]

Great Explanation!

[@yogeshvishwakarma2698]

I still have a doubt that ,,if the fluid (air) got saturated after the wbt is reached or not , or consider a example when the same air recirculate here the saturation is reached .but what about the case of fresh air?? Consider a example shown in CP arora book.

Well explained sir,but when temp. of water is less than dew temp. Of air , their will also reach that steady state . and in starting u explained that valorization takes place , but there will be sensible heat transfer from water to air and water's vapour pressure goes down and during this there is mass transfer from water to air , ya there may be some vaporization if there is vapour available( due to temp. Drop of water) is less than that value we get from pressure gradient.

What happens when cooling tower outlet temp is less than wet bulb temperature in winter season?? Why it happens??

[@arshiakhan5688]

Mind blowing that you

[@nikhilrane3042]

Thanks. Is Cooling tower sized based on summer relative humidity or rainy season relative humidity.. Do we required to increase CT fans speed during rainy season?

[@abhrajitsaha7]

Yeah, in rainy season, though latent heat i.e., evaporative heat transfer decreases or diminishes, but sensitive heat transfer increases greatly. Increasing fan speeds in CTs will help increase the turbulence and thus OHT.

[@SanjayGheji]

Nice explained Sir. Please tell, how to get "psychrometric software" you have used in above video??? Please give reference.

[@arghyaroy1819]

The temperature of the interface and the wet bulb temperature are very close to each other. Yes or no? If yes, can we easily interchange Ti and Tw in the equation relating sensible and latent heat flows?

[@satishlukka1454]

sir very good video but a cooling tower will work more efficiently on summer na because RH is very low in summer so WBT also very low.

[@SandeepAcademy9]

Yes, in summer RH will be less but since dry bulb temperature itself higher hence WBT will be also high compared to winter.

Sorry for late reply. I forgot about this. You should have reminded me. Anyways. In my College Mass transfer topics Absorption,Stripping,Distillation,Drying,Humidification & Dehumidification And Packed bed was taught very well. So I studied these topics from my class notes supplemented by Geancoplis. Diffusion etc. was not taught well. So, I watched Prof. Nishith Verma of IIT Kanpur lectures. I watched Lec 1,2,4,5,6,9. I also watched Adsoption lectures (Lec 30-34). These lectures are not important for GATE, I watched them because I had time and I used to enjoy study. As far was GATE is concerned only 1-2 questions has been asked on Adsoption in last 20 years. I do not know about 2015-2018 GATE papers. I also watched Prof. V. Kumarnan IISc Bangalore lectures (Lecture 1-9, which includes dimensionless numbers). I found them very useful for GATE and I highly recommend these lectures to any one who want to understand Chemical Engineeing in depth. Thanks.
