What is the basic relationship between depth (h) and pressure (P) under the surface of water?
P decrease with increasing h
P increase with increasing h
It does not related
Choose the correct unit of pressure (P).
N/m2
bar
Pa
All of them
Pressure is the term used for a force distributed over an area
P=F/A
True
False
The absolute pressure of the surrounding atmosphere is approximately 101.3 kPa
True
False
The gage pressure reads zero kPa of the surrounding atmosphere.
True
False
When you dive underwater, the pressure you feel in your ears increases with depth.
True
False
At the surface of water, the gage pressure on the surface of water is zero (0 Pa) no matter which system you use (tank, fishwater, sea, cup of water) .
True
False
Choose the multi-correct answers: The fluid pressure P increases with:
depth under the fluid
Density of the fluid
Gravity
Area of the surface
Find the pressure P under 1 m of the water surface. g=9.8 m/s2, density=1000 kg/m3.
9800 Pa
9800 N
1000 Pa
500 Pa
How to fnd the Equivalent force of the distruputed pressure under water in the shown graph?
F=P*h/2= 1/2*ρ*g*h2
F=P*h=1/2*ρ*g
F=P*h/3=1/3*ρ*h2
How to find the centroid of the force of the distributed pressure under water in the shown graph?
y=h/3
y=h/2
y=h*2
