A U shaped tube with diameter 2.00 cm, open to the air on both ends, contains mercury. Oil ispoured into the left arm until the oil column is 15.0 cm high. Then water is poured into the rightarm until the water column is 10.0 cm.a. On which side of the tube is the mercury level higher? Support your answer.b. What is the change in height of the mercury on both sides of the tube?c. To make the mercury return to its original level, which fluid would you have to add to thetube, and how much would you have to add (in cm cubed)?
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
A U shaped tube with diameter 2.00 cm, open to the air on both ends, contains mercury. Oil is
poured into the left arm until the oil column is 15.0 cm high. Then water is poured into the right
arm until the water column is 10.0 cm.

b. What is the change in height of the mercury on both sides of the tube?
c. To make the mercury return to its original level, which fluid would you have to add to the
tube, and how much would you have to add (in cm cubed)?
