Fluid Statics
Fluid statics is the physics of stationary fluids
Practice this chapterFluid statics is the physics of stationary fluids The SI unit of pressure is pascal and 1 Pa = 1 N/m 2
Pressure is the weight of the fluid mg divided by the area A supporting it (the area of the bottom of the container): P = mg A A fluid is a state of matter that yields to sideways or shearing forces.
fluid — a state of matter that yields to sideways or shearing forces. fluids — liquids and gases; a fluid is a state of matter that yields to shearing forces. pressure — the force per unit area perpendicular to the force, over which the force acts. density — the mass per unit volume of a substance or object.
Worked example
What does “fluid” mean in Fluid Statics?
- 1Use the wording this chapter gives for fluid.
- 2The book says: a state of matter that yields to sideways or shearing forces.
- 3Do not use the meaning of fluids. That term means liquids and gases; a fluid is a state of matter that yields to shearing forces.
Result: a state of matter that yields to sideways or shearing forces
Why. That is the meaning this chapter gives for fluid.
Do not swap fluid and fluids. fluid means a state of matter that yields to sideways or shearing forces. fluids means liquids and gases; a fluid is a state of matter that yields to shearing forces.
