We’re doing this exact chapter in my lectures right now. You helped me last sem with statics and now this sem with thermodynamics and dynamics. Bro I literally don’t know why your videos have less views and why YouTube doesn’t recommend these and I honestly don’t care but always remember you are helping a lot of students with these clear to understand videos and you will 100% get what you deserve for it 🙏
Thanks a lot!

A brief summary of the half of the course, in 14 minutes 👌🏻👌🏻👌🏻

Questions Solutions back at it again saving my grades. First statics, then dynamics, and now thermodynamics. Imma have to credit you guys on my final paper.

Thank you very much for helping me understand the thermodynamics property topic!!!

I am so stoked for this thermodynamics playlist!! You are an engineering angel and I appreciate you more than you know! Thank you for making these videos!
Sharing to all the engineering homies so their lives can also be easier.

Man, you’re a lifesaver. Incredible explanations and doing some examples at the end really drove the concepts home for me. Thank you so much!!!

[cardempire]

I am very thankful for passionate professor like you! Thank you for a wonderful semester.I had C in my IA(midsem) but I have a strong believe that wen the videos are uploaded I will get *A*

[Damn]

bro just helped me for my semester exams, life saver respect++

[ayusuryaningsih]

Thank you so much. I just found you. Your explanation is really clear. I wish that I found you earlier. I hope you can help me with my next subject in the next semester.

[katereza]

Thank you so much for making this video! I was really struggling to understand this topic!!!

[topperformanceify]

Literally just spent 6 hours doing these tables as a homework assignment, and saw this vid was posted, lol

[kevinyang-xq]

do you have any videos describing t-v and p-v graphs? I love you're explanations and those being described by you would make my life so much easier lol

[sairojithamalla]

Your explanation is too gooddd❤do more videos we will encourage you for sure

@10:50 from which table did you find the pressure value?
I made an interpolation to find the pressure at T=98 and its value was 94.6956 not 94.391

[octavianafeliz]

Hai, , I love your video so much...
but I have one question here
I want to ask "how did you get the value of Pressure of 5 cm = 94.391?, , because in the saturated water temperature table there is 98 C?" It is in the 10:55 timestamp

[calebsells]

I think it is actually considered a crime that this video has only 13 likes

[entityzero]

another fine addition to my learning materials
just one question tho at 13:16 why did u conclude that the specific volume u calculated was the specific volume of saturated vapor?

[marcjustinsasing-cqeu]

In the phase 8:00, if compressed liquids are treated as saturated liquid at given temperature. How about if it's superheated vapor? do we treat it as saturated vapor at given temperature or not?? I hope you can answer this

[ahmedreshi]

Great video. One confusion though:

At 7:42, why did you look at the pressure table and not the temperature table? The value of 125 C is there on the temp table and a value of 750 kPa is there on the pressure table, so how do you know which one to look at? Because if you look at the 125 C value on the temp table, the sat pressure for that is at 232.23, which means the liquid has already started to convert to vapour as our pressure condition is at 750 kPa so its well over 232.23, meaning it's a superheated vapour? So how do you know which one to look at in the case you are given both temp and pressure conditions, Im a bit confused.

[ibilostic]

In the last example after finding the specific volume at 100%, why did you go to the temperature table to get your final temperature and pressure? I was thinking the pressure table.
