|
Density |
How tightly packed the matter is in a material/substance |
|
|
Density equation |
ρ =m/v, m in the attic |
|
|
Specific Gravity |
Ratio of material density to the density of water |
|
|
Density of Water |
1 gm/cm³ or 1000kg/m³ |
|
|
Pressure |
How much force is pressing against a surface area |
|
|
Pressure Equation |
P = F/A, F in the attic |
|
|
Fluid statics properties |
- Pressure at given pt. is the same in all directions - In identical fluids, the pressure at a given depth is the same at all pts of equal depth - Pressure increases with depth and is directly prop. to the density of fluid |
|
|
Hydrostatic Pressure equation |
P = dgh |
|
|
Pascal's Principal |
The pressure applied to the surface of a contained liquid will be "felt" everywhere within that liquid |
|
|
Pascal's Principal equation |
F1/A1 = F2/A2 |
|
|
Archimedes' Principle |
An object immersed in a fluid will be buoyed up by a force that is equal to the weight of the fluid displaced |
|
|
Buoyant force, Fb = |
The weight of the water displaced (weight of the object in water) |
|
|
Principle of Flotation |
A floating object is buoyed up by a force equal to the object's weight |
