Calculating static pressure

  1. Oct 13, 2010 #1
    1. The problem statement, all variables and given/known data

    what is the static pressure (pt-139) at the top of the tank answer in psi


    2. Relevant equations

    P=H" * S.G. (I think)

    3. The attempt at a solution

    I took the total height of the tank it's 18 feet (216 inches) and multiplyed it by 1.44 and I got 406.08 psi


    I'm not sure which specific gravity to use, there are 2, one in the tank and another one I guess it would be in the line that attaches the tank, I'll attack the page I'm using cause it's kind of confusing without it.

    I think I did it right I'm not 100% sure though, I have another question it's the same as this question but they are asking for the pressure at the bottom tap of the tank, And I used the same formula but I only used 3 feet (36 inches) as the number so it was like

    36*1.88=67.68
