Pressure Flashcards
What is pressure
The force per unit area
Force divided by are
Measured in pascals (Pa)
What happens when a particle collides with the wall of a container
The particles exert a force on the container and the container exerts a force on the particles
Equation for pressure exerted on the bottom of a container by the fluids weight
Pressure = Mass x 10 x Cross sectional area
Pressure = density x depth x gravitational field strength
At what angle is force exerted on a surface
Right angles (the normal) to the surface
Equation to find mass of a fluid
Density x volume
Equation for volume
Height x area
What is atmospheric pressure
The pressure due the a weighs fluid due to the weight if the air above it
What is 1 atmosphere at sea level
1.01 x10^5 N/m^2 = 101kilopascals
