    "As you go deeper into the liquor, the more pressure you should have". Funny, as the university work piles up, the more pressure I have and the deeper into the liquor I sink

      My advice would be learn as much as you can and start building networking/find internships during summer and have fun.

    If we exchange the gas with a liquid, will it be the same as all the dots have the same pressure or it will vary ?

    • @fahadalkhirsan4527
      @fahadalkhirsan4527 2 ปีที่แล้ว

      I think it will vary since the weight of the fluid will add more pressure than the weight of the gas!

    We had a problem like this on an exam except the fluid was of "unknown density." Any ideas?

    • @Engineer4Free
      @Engineer4Free  7 ปีที่แล้ว +3

      You can just rearrange the formula P = Po (+ or -) rho * g * h to solve for rho, which is the fluid density! Remembering that pressure increases the deeper you go down in a fluid. It's worth checking out my other fluids tutorials here just to get more familiar with the formulas: th-cam.com/play/PLOAuB8dR35oeOIPMOBH6hjwobuIJHPKSN.html

    What if h is missing?

    • @Engineer4Free
      @Engineer4Free  5 ปีที่แล้ว +2

      Then h is the unknown and you must be given all other quantities. Just rearrange for h and solve. At most you can have 1 unknown, so the question can be framed in a few different ways such that you must determine whatever the unknown is.

  • @muhammadebrahimali4351

    When do we add Patm to pgh

    • @Engineer4Free
      @Engineer4Free  6 ปีที่แล้ว

      When you want to know the pressure in a fluid that is at depth of h below the surface of the fluid that is in contact with the atmosphere. Sometimes with manometers due to the U shaped bend there can be a location in the fluid column that is higher than the boundary with the atmosphere. In that case you subtract ρgh from Patm.

  • @SurajYadav-ln6kq
    @SurajYadav-ln6kq 7 ปีที่แล้ว +1

    Sir one think i did not understand that what is Po

    • @Engineer4Free
      @Engineer4Free  6 ปีที่แล้ว +2

      Po is just a known pressure. Usually in problems like this you start with Patm as Po, and then you will add ρgh to determine the pressure at the deeper depth. In compound manometer problems you will then repeat the same equation, but you will use P from the last iteration as Po in the new iteration. If you go deeper into the column in the next iteration, you add ρgh and if you go up higher into the column you subtract ρgh.
