    This is the best explanation I've ever come across. The video is good... you just have to calm down to actually hear everything he said.
    It isn't his fault... You all should try learning his own language to see if anyone will understand you. He's a great teacher... thumbs up man

      I didn't intentionally come to learn from you. I thought this was a white person who could speak clearly.
      I'm here because I want to learn this, obviously. It's funny that you're telling me to learn from him... I CAN'T learn from him... that's the point of this comment. Are you confused? Can you read?!

    Good video! Concise and informative. Like someone has said if you are knowledgeable in your work you can easily understand what he says. He is trying to help students like us, so if you do not have anything nice to say then rather not say anything at all. If you do not like the video then simply look for another one.

  • @PGIFilms
    @PGIFilms 7 років тому +3

    For those that find this video a little hard to follow, change the video speed under the settings (Gear) icon and slow it to 0.25 or 0.5 when you play it. The main issue is not necessarily the accent and pronunciation of the English words, it's the speed at which he is talking that magnify the distortion of the way the words are being pronounced.

    Tip : As​ @4001Jester suggested turn on captions and play at 0.75x speed. Plus ( I say ) mute the sound so you won't get distracted by the accent.

  • @mansu3310

    For the people who doesn't like his accent, go and watch the video that you can understand the language. I am from USA, a large portion of population here doesn't speak any English at all. Yes it is not clear, but the instructor in this video is not from a native English speaking place, and I wonder unlikely to many video presenters with very hard accents why so much back lash against his language skills than the information he delivered. American colleges and universities are filled with foreign taught educators with different kinds of accent.

    So a closed system can be influenced by outside energies, like Earth wich shares similar perfectness as vacuums? Some say water vapor is chaos and snowflakes are order by magical turnings.

  • @NAYAN-t3e
    @NAYAN-t3e 2 роки тому

    • At any instant in time, the total energy content in the system remains unchanged & hence, the steady state.
    • So, the net fluxes of energies through transport of masses & transfers of external heats & works through system boundaries which bounds its own volume are balanced at any or each instant. Hence, steady state is assumed.
    • Rate balanced law is valid at each instant in time but overall energy law is valid for complete time period.
    • Loss terms either on rate basis or overall basis are to be accommodated in the equation to maintain overall balance at each instant throughout the domain of application.
