Psychrometry, Processes on TS diagram

[@kushagrak960]

Sir your videos are too informative, I really appreciate your hard work you put in through. Thank you so much.

really wonderful 👍👍

Bro in thermodynamics "saturation" word is confusing liquid air vapour steam please one video on this point.... Thanks

[@kanchanabhishek7150]

Sir ur video is superb in quality wise

[@journeeunbound]

Wonderful Sir...I still remember you explaining us the 4-strokes of SI engine using a dummy in Gyan Vihar mech block...it was my second year...can't forget the way you explained that whole process...thanks for such good lectures sir👍..I was in 2009-14 batch..M.tech DD (M.E + E.E) ! God bless you🙏

Very good and professional explanation ,thanks sir

Can we plot the changes in air property in these process on TS diagram ??

[@JaiSingh-vu4lw]

good vedio for basic understanding

At 42 deg, water in bowl is converted to vapour. From where this latent heat came?

[@Allinone-nr7uh]

Dear sir, Thanks for the lecture. But at 42 degree Celsius if i put water of different temp., what will happen? i mean what you r showing on the T-S diagram (ex: 38* at 0.0662 bar) is the condition after completion the full evaporation. At first stage water should evaporate at much lower temp as initially the pressure inside the bowl is very low.

[@Dr.AmitMandal]

No, initialy, air is inside the box at one bar, however completely dry.

[@jagnandantomar1079]

Good explanation sir

[@XploringIITBwithDhananjay]

You are great sir... please make videos on entropy topic

[@Dr.AmitMandal]

Already there in my channel

[@vigneshwaranrm6277]

Sir one doubt, when we keep the water at 42c its temperature will increase and using this rise in temperature it will evaporate and mix with air, however the temperature change (phase change) it not appreciable as the rise in temperature, then how can we say that the water gets cooled? Though its initial temperature was lesser than 42c.

[@Dr.AmitMandal]

Elaborate it more

Sir plz make a video water vapour,steam saturated vapour and superheated vapour..

[@Dr.AmitMandal]

Find my lecture on properties of steam....

Nice video sir....kya aap ac motor ka working bta skte ho next video pe aur squirrel cage rotor aur slip ring induction rotor ki videk banakar unki construction bta skte ho plzz...

[@mohdkhaled9895]

Sir i have doubt,, air has 2 components(Dry Air+ water vapour) Humidity Increases as water vapour content increases in atmosphere,, but for water to get converted into vapour it needs 100 deg cel, at 1 bar So in atmosphere we not proving 100 deg cel,, then how it's getting conveted into vapour and how leading to humidity increase If you say sir,, here saturation pressure is less than 1 bar,,, so at lower temperature its converting into vapour,, then if it's like this,, then all water should start boiling na sir,, without providing it heat

[@Dr.AmitMandal]

Strictly speaking, boiling point is the point where the liquid emanates vapor with a pressure equal to or slightly greater than atmospheric pressure. At low temperature the vapor just making a mixture with atmospheric air . That mixed vapor has some pressure with it.
