    New research is showing that it's much more important how hard you're working than how "quick" you are at understanding things. Props for going out of your way to learn! And you're welcome.

      Are you able to findout aniroid barometer efficiency in joules terms
      Are you do this whole work in terms of joules so we found how much work done and how much maximum heat we can produced by zig zag motion of outlet pipe
      Since hot water is required now a days

    hello ...thanks for sharing man. However what happens if at point 2 the pissing bottle wasn't exposed to the atmosphere? Say it flows through a pipe and we wanna know how much pressure the fluid would exert at say the end of the pipe (not exposed to air) but attached to a manometer or Cork?... if we were to measure this pressure at this point, what would it be?...certainly it shouldn't be atmospheric right?

  • @georgethomas4889
    @georgethomas4889 9 років тому +1

    Why is the pressure the same at 1 and 2? Surely the pressure at any point along the horizontal distance at y=0 is affected by the weight of the column of water above it? So it seems intuitively, at y=0, that you have the pressure of 1 atm acting in the negative horizontal direction (left), and the pressure produced by the weight of the column of water above y=0 acting in the positive horizontal direction (plus 1 atm). So how is the resultant pressure the same at 1 and 2?

    • @DocSchuster
      @DocSchuster  9 років тому

      +George Thomas Nice description! I agree with what you've written. Maybe I meant that both 1 and 2 are atmospheric pressure?

    • @georgethomas4889
      @georgethomas4889 9 років тому

      I don't understand how they can be the same though. It seems that the pressure at 1 should be greater than that at 2. I don't think you're wrong because the exactly same explanation is given in my textbook.

    • @dulak6048
      @dulak6048 9 років тому +1

      +George Thomas He is looking at the pressure exactly outside the hole. Because the pressure outside the hole is not in the body of water then it is equal to the atmosphere (his label for P2 should not be drawn inside the can). You are right though that, in principle, pressure at the bottom of the can is greater than the top due to the weight of the water

    • @georgethomas4889
      @georgethomas4889 9 років тому +1

      That's a very clear explanation thanks. I think I understand it now. For a small column of water just inside the hole there is a pressure difference due to the weight of the water above which causes the column to accelerate. Just outside the hole there is no pressure difference so the column moves at a constant speed.

    • @surya8891
      @surya8891 8 років тому

    The last minute and a half of this video was so great I felt compelled to find a question to ask about the video:
    In this case of the purple container-brown liquid situation, what you're (technically, Torricelli) saying is that the height of the liquid in the container as it falls will always match that of the height the "escaping" liquid peaks at, correct? So long as there is liquid "escaping"

    • @DocSchuster
      @DocSchuster  11 років тому +1

      Yup! Barring friction. How many times have you seen sqrt(2gh)?!? Really, it's just MEi = MEf.

    • @DocSchuster
      @DocSchuster  11 років тому +1

      Oh, did I say ALWAYS? I mean, only if the spray is directed straight up.

    • @DocSchuster
      @DocSchuster  11 років тому +1

      ...and then only if the rising liquid is not also colliding with falling liquid that rose earlier (the fountain effect).

  • @ORagnar

    I'd say that the hard part was the assumption about the pressure at the hole. It was a good assumption, but I wouldn't have been so certain about it, which is where the value of actually doing experiments comes in.

    In the Bernoulli equation, you used y1 as the height for the liquid in the container. Wouldn't it be more appropriate to use (y1)/2 as the height because that would be the center of mass of the liquid?

    Doc, shouldnt the pressure at the hole be pgy

    why do we always consider the pressure outside the container and not what is from the inside

    @martinaaylmer5841 9 років тому

    The Bernoulli equation is derived using the conservation of energy.The energy within the fluid consists of pressure energy, kinetic energy and potential energy. Kinetic energy is 1/2m v squared not 1/2 Rho v squared. In this case the velocity of liquid within the tank is zero and the kinetic energy therefore is zero.But Bernoullis eqn is written incorrectly.
