    I am also confused why you didnt include atmospheric pressure, compared to the first problem you did that was looking for the specific gravity of oil.

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 21 день назад

      Think of this as a water tank (or a bucket, if you will). Adding opposing forces to the tank (Patm.Area) will cancel each other. So you can include Patm, but you need to include from outside pushing in as well.

    I am also confused how you got 4PiR, if you're referring to an inner and outer diameter

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 22 дня назад

      The thickness of the ring is negligible, hence 2PiR for inside of the ring touching the fluid + 2PiR for outside of the ring touching the fluid= 4PiR

      Agreed! Thats one of the points I am making in this video. Just because math says you can doesnt mean you will be able to in real life. Best of success in your studies.

  • @lightningtech8025
    @lightningtech8025 Месяц назад

    I used linear interpolation because it is approximately linear across a small difference. On the FE I will likely skip linear interpolation for the sake of speed and time management, but is this an appropriate solution if I felt I needed to use it.

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 22 дня назад

      Sounds great. You have to do what you have to do. It is good to strategize before taking the FE. Smart.

  • @lightningtech8025
    @lightningtech8025 2 месяца назад

    Why do you use the velocity of the top plate relative to the bottom plate? Would we not use the velocity of the top plate alone, because the fluid is still, so the velocity of the top plate relative to the fluid would just be the top plates velocity, or is it assumed the fluid is moving with the bottom plate?

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 21 день назад

      Good question. Yes, because of the no-slip condition, the first fluid particle touching the bottom plate will move 1m/s toward the left. Also, if it makes you more comfortable, you can think of this question as the bottom plate is stationary and the top plate is moving at 3 m/s (2-(-1)) to the right. The final answer will be the same.

    Not having pressure was a large omission.

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 22 дня назад

      Please note that that "cube" is the size of one of your hairs, as this is a differential analysis. Hence, the pressure change is negligible for a small size and reasonable assumption in real life.

    how does the bernoulli equation affect manometry

    • @CollegeFluidMechanics
      @CollegeFluidMechanics 21 день назад

      This is a good question. If you insert V=0 into the Bernoulli's equation (fluid in a manometer is stationary), and manipulate the remaining terms, you get DeltaP=rho*g*h, which is the same equation presented here. So, Bernoulli's equation is a very powerful concept to learn in fluid mechanics

    I am curious, Wouldn't the L defined in the FE handbook as "Length over which pressure drop occurs" be the vertical distance AKA 10 sin(30)?

    • @talltales845
      @talltales845 17 дней назад

      L is the length of pipe. Vertical distance in a situation like this is accounted for in Bernoulli’s equation, where it is represented by the difference between the two points of height z1 and z2.
