    Hi, my textbook has a exactly same problem and it says consider the fact that the density for water is 1000kg/m^3, the solution also used 9800 but didn't explain why. Could you explain why you used 9800 here?

    • @QuocDatPhung
      @QuocDatPhung  Год назад +4

      As you already know, the density for water is 1000kg/m^3. But we have to account for gravity acceleration which is 9.8. So if you multiply the two together, you will get 9800. But that's only if the tank is measured meters. If it is in feet, then the you must use 62.5 instead of 9800. At the end of the day, the easiest way is just to remember these two numbers, 62.5 and 9800. It's not really important where they come from. Let me know if that makes sense!

      @@QuocDatPhung Thank you so much! So if it's water tank or bucket problem we always need use these two number? BTW Your videos are amazing .

      @@rebeccalan8778 Thank you for your kind words Rebecca! And yes, just remember those two and you're good to go! There are about 5 kinds of tanks you should know (circular tank, rectangular tank, triangular tank) and each are slightly different from each other. I go through how to deal with each kind in my playlist here: ruclips.net/p/PLeTO6OT3-FKmuCeO97iKt_Aibx-a938JA

    Why isnt the distance (y-1) instead of y, I dont understand please help

    • @QuocDatPhung
      @QuocDatPhung  7 месяцев назад +1

      At 1:27 I defined y to be the distance that a slice of water needs to travel to get to the top. So, the distance must be y as defined. Let me know if that makes sense.
