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:
150 cm2
Step-by-step explanation:
double of triangle abc is 200
this is in middle of both
Answer:
A
Step-by-step explanation:
Since its parallel to y=3x+1, the slope must be the same so now we are left with A and D. If you put (1,2) into A, it is true so it is A
The answer is 138
Because the angle is 180 and what I did was 2 x 21 = 42 and I did 180-42 equals to 138
The answer is 0 because any number - itself is equal to 0
