Find the force pushing out on a flat viewing port in a large,
closed storage tank. Fluid in the tank has a specific gravity,
gamma = 0.87, and the pressure of the vapor of the fluid is
17.3 psia. Depth d is 6 feet. Height H = 1ft and length =2 feet
(Note the positive z-direction is pointing from outside to
inside).
Note: Please explain each step clearly and why you did those
steps. I will rate high if you explain the process correctly.
The final answer should equal to F = -5689 lb.
