a glass container was filled with oil with a density of 0.80 g/cm^3 up to 9 cm. in height.
1) what is the pressure at the base of the container?
2) what is the pressure if depth is 3 cm. from the surface of the oil?
3) what is the pressure if depth is 4 cm. above the base?
I will be glad to critique your thoughts.
Pressure is the weight per area of the fluid above. If you do not include the atmosperhe above, you are measuring "gauge pressure" above atmospheric pressure.
