Pressure Flashcards
1
Q
Pressure, p
A
Force acting per unit area.
p= f/a
1 N/m^2= 1 Pa
2
Q
Why do fluid exert a force?
A
Fluids have weight, thus they exert a pressure as well.
3
Q
Pressure at a point due to a column of fluid
A
p = hpg
4
Q
Air pressure
A
Air pressure is due to collision of air molecules. Hence, when there’s less air molecules, there is less air pressure.
5
Q
Equipment to measure atmospheric pressure
A
Barometer
6
Q
Equipment to measure pressure difference
A
Manometer
