10 Questions
Gauge pressure is determined by comparing the total pressure of a fluid between absolute and atmospheric pressure.
True
Absolute pressure is measured in relation to zero pressure in the empty vacuum of the universe, denoted by 'abs.'
True
Brownian motion is the constant and random movement of all fluid molecules, causing a fluid at rest in a vessel to exert force on the vessel's walls.
True
Absolute pressure occurs when all air is removed, creating a perfect vacuum, and there is no concept of negative absolute pressure.
True
Pressure is a measure of force per unit area, calculated by reference to a vacuum or airless space.
True
Absolute pressure is measured with reference to a vacuum or airless space.
True
Absolute pressure occurs when there is no concept of negative pressure.
True
Gauge pressure is determined by comparing absolute pressure and atmospheric pressure.
True
Brownian motion is the constant and random movement of all fluid molecules.
True
Absolute pressure is measured in relation to zero pressure in the empty vacuum of the universe.
True
