This is the best problem solving video I've ever seen, I swear. More power to you!!

There is a correction at 9:40 in question-5 we got the capacity 8626 in KJ/min., So kindly divide it by 60 to get capacity 144 in KW.

plzz be slow..and dont add background music to it plzz!👌

this video helped me to learn psychrometry very easily in just a fraction of minutes.thank you very much...keeping doing such videos again and again

This is the best problem solving video I have ever seen!!!

An air conditioning system using 80% outdoor air and 20% recycled air has the following designed conc Indoor: 24°CDBT, 60% RH Outdoor: 32°C; 15g/kg water Sensitive heat gain 48kW Latent heat gain 16kW Air leaves the cooling coil saturated and is blown at 16°C DBT 236 (1 A) Answer the following questions 1. Give a synoptic air flow diagram of the described system 2. Extract the characteristics (DBT, WBT, H, RH, w, v) of both the internal and external airs fr psychrometric chart. 3. Calculate the mass flow rate of; a. The supplied air b. The recycled air c. The outdoor air 4. Find the characteristics (DBT, WBT, H, RH, w, v) of the air at the inlet of the coiling coil 5. If the by-pass factor of the cooling coil is 0.15, deduce the value of the contact factor. 6. Determine the surface temperature of the cooling coil. 7. Calculate the sensible and latent loads on the cooling coil. 8. Deduce the sensible heat factor (SHF). 9. Calculate the power of the cooling coil. 😢😢😢😢

one of the best videos that i have ever gone through

Best video on Physchometric chart ...keep up the good work mate

very useful video sir especially before exams thankyou MR I.Y.

It was the best video for psychometric chart numerical tomorrow is my exam and i am new to this topic thanx to you sir for teaching us through KZfaq.😊

Very useful nd now i got confidence to attend these problems in univ xams

thank you so much sir you gave me 10 marks 😊

pick 1 language per video. Aside from that...... spot on man.

Conceptual and physical understanding need to be focused while solving the problem. For Example : if the object is at 100 deg F temperature people know and feel what such a temp is. Such type of understanding required from your videos. .which will add more value to your videos and as well viewers understanding

Very helpful.. better if the video with power point presentation.

Really it helped because I was too confuse and tomorrow is my exam...😅😅 Thank you so much for this video..👍👍😊

Covered many types, nice vid👍

You really helped me for tomorrow exam 🙏 Thanks for the explanation bro...👍

Clear explanation of how to solve pyschometric chart questions...thanks

It is very much interesting and knowledgeable video I have one ☝️ question what is the SHF formula is it H3 - H2/ H1- H2 ( shown in 5th question ) or H3 - H1/ H2 - H1 ( shown in 6th question )

Very helpful , thanks 👍

The model is available on redslibrary website. One click and you can calculate everything without trouble. The model is in simulink model

In question no. 2 the formula for heat added = mass flow rate *(change in h) But in question no. 6 heat added is just change in h. Is there any mistakes or any reasons for that?

Thank you brother it is really helpful

Best vedio for psychrometric chart

your teaching concept is unique sir please be continue it helps someone thankyou

Hey buddy, great video. Small correction. In 6min12sec, the unit of the mass flow rate should be kg/min instead of the m³/min of the volume flow rate So 185.2 kg/min

Tq bro u explained well i can just answer by giving any questions

Most powerful video. Thanks sir

Thank you so much for this You made my psychometry so easy

1:59 Pv is coming out to be 0.0078 bar. By mistakenly you had written it 0.07926bar. By the way best video I saw for this topic. Thanks 👍🏻

Sooooo Much Helpful...... Cleared Pyschrometry Doubts.... Thanks Alot.....

Very easily explained 📈

the best playlist

This type of problems like we have to find:- 1) total heat transfer in kw for air flow rate of 100 metrecube per min 2) bypass factor of cooling coil if coil surface temperature is 22 degree c

Thanks for making this video, it will help many. In question number two I bit confused regarding RH curve as you are covering 50% but writing 40%.

you are really savior for me. jai ho

You are the best teacher thankyou sir

Best lecture of psycometrichart thanks sir.

Bro your explainatoin was superb

great view with good and explained problems thanks papa

mostly question covered in this video, in easy way solve problem thank sir

Quick and simple, thumbs up.

Thanks for this video This is best problem solving video

Bhut hi bdiya video h. Sb clear ho gya

more confidence gain by this video, in this topic

wao this is called teaching.welldone sir....

thank you alot this video helps me in my exam ❤️❤️

Nothing to say bro ...... excellent job

Please no background music 🙏

thank you for the video,helped me so much

Thanks for Excellent lecture. I learned something.

Can anyone please solve below An air conditioning system receives 3kg/s of Outside Air at 38o C with a dew point of 9o C (call this point A), which is mixed adiabatically with 7kg/s of Return Air at 27o C, Φ=80% (point B). The resulting mixture (point C) is then cooled until its specific humidity is 11.8g/kg (point D). It is then mixed with additional Outside Air (point A again) such that the new mixture is at the Supply Air condition of 25o C, Φ=50%. (point E) Using the psychrometric chart, (a) Determine the amount of heat removed from the system between (C) and (D) (b) Determine the mass flowrate of additional outside air required to get from (D) to (E) (c) Sketch the whole process on a sketch of the psychrometric chart.

Your teaching is amazing Just slow down your speed, it would be easier to grasp!

please remove the tuening from background it will good to hear lecture

awesome video sir psychometric problem is now solved

very useful video sir we want more question on this topic. thankyou

Thanks a lot sir ... I think it's enough problem And happy teachers day sir

Good examples, good explanation!

Very helpful video!

very useful video sir....please can you add some video on duct design by equal friction & velocity reduction method

Hi Sir. May I ask you questions? How if there's no relative humidity or one of those indicators is missing? And what specific table I should use to complete? Thank you

superb work nd nice explanations keep it up..🖒🖒🖒

nice explanation...but there was some errors in viewing chart.but overall the concept was easily explained ..

Good job sir. Keep uploading​.👍

If the heating is to be from 30*C DB and 90% RH to 30*C. The cooling is to be from 27*CDB and 70% RH to 30*C. What would the moisture content (grams water per kg of dry air) be and the enrhalphy of the air (KJ per kg). How would this look like on the psychrometric chart? Thanks

Very good video but please remove the background music please.........

Thank you. Really useful

Sir please solve adiabatic mixing of steam without using chart but using table

Great examples

Awesomeee Sir salutes u

Thank you so much sir!

Can you please provide pdf of the psychometric chart you have used?

excellent video brother....thank u soo much

Thanks your vedio help me in the exame . thanks

Thank you so much for this!

Can You Send me all the formulas related to this

Very helpful and valuable !!

Sir..Plz upload more lectures of RAC..

really helpful.. great work!! waiting for more such videos

Pls upload a video on numericals related to ERSHF,GRSHF,RSHF...

thanku so much sir it's quite very very helpful for mee

keep doing the good work

very usefull video sir more que solve by book......thnks sir

It's awesome video sir Thank you sir

Hey, Thanks for this video, this is really helpful =)

badhiya samajh aaya...dhanyavad

Excellent teaching 😍😍

Sukriya sir ji....😊

Pls advise how to calculate reheat for humidity control.pls give examples

The answer for pv is 0.0079 not 0.079 pls recheck

Thank you so much sir ❤❤❤

great sir,its really helpful..

what if the pressure is not remain constant in this process ? for example: air compression by using a compressor. we know that, inlet pressure is 1 atm, and the outlet pressure is greater then.

very helpful explanation sir

very helpful .. thank you sir ..

The sensible heat factor scale is also given in the chart, then without using the equation, how can SHF be found out using the chart only?

Sir why the formula of heat added change in 2 different sum 3:18 & 12:12

Thank you sir.

Nice Work...
