So, do I do 2.5d..?And 2.5d seems to do the trick since I got the correct answer with it: F = PA = pgdA = 1000*9.8*(2.5*7)(7*7) = 8403500 N Thanks a bunch :-) !

HELP! L-shaped tank problem! Homework Statement The L-shaped tank shown below is filled with water and is open at the top. (a) If d = 7.0 m, what is the force on face A due to the water? (b) What is the force on face B due to the water?Homework Equations F=PA P=pgh The Attempt at a Solution...

Thank you so much! I think now I know the concept behind this probelm :-)

So... the water pressure at the bottom of the barrel is: P = phg = (1000kg/m^3)(3.6m)(9.8m/s^2) = 35280(Pa??) and since F = p*a, (35280)(area of the bottom of the barrel) = force (35280)(0.6^2)(pi) = 39880.512 Nand the grativational force on the water contained in the barrel is: mg = pvg =...

Would the water pressure at the bottom of the barrel be: pressure of the tube on the top + pressure of the water in thebarrel -> pgAh + pgAh -> (1000kg/m^3)(9.8m/s^2)(0.00046m^2)(1.8m) + (1000kg/m^3)(9.8m/s^2)(0.6m^2)(pi)(1.8m) -> 20021.4 ? Does hydrostatic pressure depend on the area...

Homework Statement In the figure below, an open tube of length L = 1.8 m and cross-sectional area A = 4.6 cm2 is fixed to the top of a cylindrical barrel of diameter D = 1.2 m and height H = 1.8 m. The barrel and tube are filled with water (to the top of the tube). Calculate the ratio of the...
