Answer: F = 211312.5ft/lb.
Step-by-step explanation: Hydrostatic pressure is pressure caused by a fluid due to the force of gravity. It is calculated following the formula:
P = ρgh.
ρ is the fluid density (62.5 lb/ft³);
g is the gravitacional acceleration( 32.2ft/s²);
h is the height of the fluid columm;
P = 62.5.32.2.h
Pressure at h = 1ft:
P = 62.5.32.2.1
P = 2012.5 psi.
Now, hydrostatic force is F =
The pressure exerted on the surface is not constant. It depends on the height. So, to evaluate the force:
dF = P(h) dA
Since it a rectangular plate, dA = w.dh, where w is its width and equals 6 and dh is its height element.
That gives: dF = P(h)w.dh
= 2012.5.6. = 2012.5.6() = 12075() = 211312.5ft/lb.
Answer:
3.75 feet.
Step-by-step explanation:
Given:
The volume of a right octagonal prism is 30 cubic feet.
The area of the octagonal base is 8 square feet.
<u>Question asked:</u>
What is the height of the prism ?
<u>Solution:</u>
<em>As we know:</em>
<em />
Therefore, height of the prism is 3.75 feet.
It would come out as an error because you cant divide nothing by nothing. There is nothing there to divide
Answer:
B.
Step-by-step explanation:
4 is of course not equal to 5 so no values of x make the equation true.
There are no solutions to this equation.
