Study Notes
Pressure Concepts
- Gauge pressure is the difference between the absolute pressure and the atmospheric pressure.
- At a depth of 10 m in water, the gauge pressure is 1 atm, which means the absolute pressure is 1 atm + atmospheric pressure.
- The value of atmospheric pressure is 1 atm (standard atmospheric pressure).
- Negative pressure is a pressure below atmospheric pressure, creating a partial vacuum.
- An example of negative pressure is the pressure inside a drinking straw when you suck on it, which is less than atmospheric pressure.
