Pressure: Example
About the Lecture
The lecture Pressure: Example by Jared Rovny, PhD is from the course Fluids.
Included Quiz Questions
Which of the following statements about gauge pressure is CORRECT?
- Total pressure minus the atmospheric pressure is called gauge pressure
- Total pressure exerted on an object is called gauge pressure
- The amount of pressure equal to atmospheric pressure is called gauge pressure
- Total pressure minus double the atmospheric pressure is called gauge pressure
- Vacuum pressure is called gauge pressure
What is the approximate gauge pressure at a depth D = 5,000 m of water ? Atmospheric pressure = 100 kPa and gauge pressure P = ρgh.
- 50,100 kPa
- 5,100 kPa
- 5 x 107 kPa
- 50,000,000 kPa
A tube of height 1 m is filled with water. Another tube of the same height is filled with mercury. How do the gauge pressures at the bottom of the tubes compare ? (Density of water = 1 g/cm³, density of mercury = 13.6 g/cm³)
- The gauge pressure at the bottom of tube filled with mercury is 13.6 times the one filled with water
- They are equal
- The gauge pressure at the bottom of tube filled with mercury is 1/13.6 times the one filled with water
- We need to know the thickness of the tubes in order to be able to comment on the pressure
- The pressure of the tube filled with water is more than the one filled with mercury

I'm so glad that am starting to learn physics with professor Jared, he's excellent. I used to use youtube and the organic chemistry tutor or khan academy to prepare for the Mcat,but professor Jared is at another level.
