1. The problem statement, all variables and given/known data The L-shaped tank shown in the figure is filled with water and is open at the top. If d = 4.81 m, what is the total force exerted by the water (a) on face A and (b) on face B? image: http://edugen.wileyplus.com/edugen/courses/crs4957/art/qb/qu/c14/fig14_33.gif 2. Relevant equations F=A*p 3. The attempt at a solution For A I believe the solution should be 1000*9.81*2d*d^2 = 2183404N and B should be 1000*9.81*2.5*d*d^2 = 2729255.8N but these both seem to be wrong. Based on other solutions to the same question found around the internet, this should be the solution as well, but apparently it is not. Unless atmospheric pressure is supposed to be factored in, which I doubt it is, I have no idea why this is wrong.
