Help solving / check fluid force

  1. Aug 20, 2014 #1
    I have a vertical panel. Top of panel is at water level. Units are in feet. 15'x5'. I calculated the force in pounds. water=62.5 lb/ ft3. I came up with F= 11,718.75 lb
    Just double checking this, making sure I did I correctly.

    Hard to tell without more info. Please state the entire problem, exactly as given.

    My calculations were 11718.75 pounds. Just trying to verify my answer. I want to make sure I did the integral correctly.

    Nice: a weight (oh, sorry, a force...) in seven digits when the height is given in one.
    The integral is correct.

    But boy, am I glad I was taught SI units....

    Still don't see the problem, exactly as given; do you, o gut peeker ?

    Yes, the answer is excessively precise.
    The second diagram explains the question well enough, I think. In the OP, I had to assume the answer correct to deduce the question.

    This looks correct. (Oops, I was doing PF with my Iphone, and didn't notice the other responses).
