Chem/Phys Units and Equations Flashcards
1
Q
Pressure exerted on an object submerged in fluid is equation to
A
Density of that fluid x acceleration due to gravity (g) x depth of submersion (h)
2
Q
Gauge pressure=
A
Pressure of the system in absolute terms- atmospheric pressure
3
Q
Absolute pressure=
A
Hydrostatic pressure (pressure exerted on an object by the fluid it is submerged in_ + atmospheric pressure (pressure exerted on the object by the ambient atmosphere)
4
Q
At higher elevation, what happens to pressure?
A
Decreases!!!
5
Q
% an object submerged=
A
Density of the object/ density of the liquid x100 or volume displaced/ volume object x 100
6
Q
Buoyant force=
A
Density of water x volume of water displaced x gravity
7
Q
Change in P for piston systems=
A
F1/A1=F2/A2
