Main Question or Discussion Point
I am not sure how to calculate any of this or if i am even doing it correctly. I pulled these formulas from different sites and not sure if I applied them correctly. Or even if these were the right formulas to apply.
**I also did all calculations acting as if the bladder was square and had not round corners.**
1. The problem and given/known data. ( the attached PDF shows the data and shape of the bladder)
Calculate the total force, on the bottom of the bladder.
2.Equations used
Pressure= force/area
Force= length x Width x Height x water density
Area of bottom in square inches= width x length x 144
3. My attempt at a solution
First I solved for force
Force= length x Width x Height x water density
15.166 x 7.166 x 6 x 62.5
f= 40,754.831 lbs
Next I solved for area of the bottom
Area of bottom in square inches= width x length x 144
A= 7.166 x 15.166 x 144
A= 15649.855 sq in
Then I solved for pressure
Pressure= force/area
p= 40,754.831 lbs/15,649.855 sq in
p=2.604 lbs/sq.in.
I understand that pressure increases as the depth increases... so pressure isn't the same in all levels (right?)
But does any of this make sense or seem right. Any help or insight on this problem is greatly appreciated.
