Thank you so much for your videos!! Anyone struggling with this course is undoubtedly paying someone who isn't teaching them well, yet your videos are open to anyone who needs it!
@@engineeringdecipheredOh I see, one more thing professor .if fluid properties may change from one location to another(from inlet to outlet) , how right side of the equation can be zero like at 4:11 ?
You can download the blank notes - there’s a link in the description. For the filled in notes, you’ll have to fill them in yourself while watching the video.
Question 1: Sir, you have written that in general, there is no change in Kinetic Energy and Potential Energy in case of turbine and compressors, how is that so? Because, considering the fact that they are producing or taking in work from a fluid, how can the kinetic energy or potential energy not change or inter-convert due to compressor blades or turbine blades? Question 2: Sir, in case of throttling valve, you wrote that there is no change of velocity (and hence /\K.E.=0), why is that so? Considering the Bernoulli Equation, we get that change in pressure leads to change in velocity, so why does the Kinetic Energy not change in this case?
this is all in general: if you are given the velocities - then calculate kinetic energy. If you are given heights - then calculate the potential energy. I think a change in 100m only leads to a delta E of 1 kJ/kg? And 45 m/s is only 1 kJ/kg. So they are usually orders of magnitude smaller than the other values in the equation so we can just neglect them.
the last good luck that he said, means that we're litteraly FUCKED😂😂😂😂😂 thank you thank you thank you sooooooooooooo muuuuuch to made this easy for us!!!!!!!!❤🔥❤🔥❤🔥
My man, you deserve hella more views, you made this so much more simpler than any other source I’ve gone to. Thank you so much!
you deserve a huge round of applause bro!! you are doing engineering community a great service !!! Hats off 👍👍Undoubtedly great content !
Hey bro,
Do you have any videos uploaded for Heat transfer for Yunus Cengel ????
I'm a engineering student from Brazil and your videos are helping me a lot in my thermodynamics exams, thanks man!
This is amazing! You've made this so simple and easy to understand. I've already shared this with my peers taking this course. Much love

My man saving me from my downfall in the first sem
This was beautifully explained, loved how u started every sing scenario with the steady flow eq and built up from there, much easier to remember too
Absolutely amazing. Thank god I found this.
Hello from London. :)
Thank you so much for this video. I was so confused with all these terms from bernuelli equation and this energy equation...
This is really the best! Thank you
is there a simple way on How one can determine if a problem falls under steady flow, Non-flow or 1st law?
In the steady flow energy equations, the work is shaft work with simbol of Ws.
Thank you so much!
thank you for the amazing knowledge you are sharing
At 9:11 does _1 inlet/outlet_ mean *1 inlet or outlet* or *1 inlet and 1 outlet* ?
1 inlet and 1 outlet!

i will be very thankful if you provide the pdf download link of your leacture.Because your lectures are amazing man.God bless you.

And I think you're right in that the velocity does change in a throttling valve, its just negligible compared to the other values.
@@engineeringdeciphered Right Sir.
Appreciate your answers Sir, they are helping me alot, Thank you :)
by book has work subtracted. Is that just because its using a different sign convention?
i have the same question did u figure it out?
@@dihanmahmood132 I don’t remember, sorry ur in thermo rn that shit sucks.
SUPER COOL
I love you you are the best
Thanks man ♥
