Definition
 ρH2O=1 g/cm3 or 1000 kg/m3
Term
 Specific Gravity Equation
Definition
 SG=ρ/ρH2O
Term
 Pressure Equation
Definition
 P=F/A
Term
 Pressure of Static Fluid
Definition
 P=ρgz: where z is the depth of the object under pressure
Term
 Absolute Pressure
Definition
 P=Po+ρgz: where Po is the pressure at the surface
Term
 Gauge Pressure Equation
Definition

Term
 Buoyant Force Equation
Definition
 Fb=ρwaterVobject submergedg
Term
 Archimedes' Principle
Definition
 The buoyant force is equal to the weight of the fluid displaced Weightfluid displaced= ρgV
Term
 Pascal's Principle
Definition
 For an in-compressible fluid, change in pressure will be distributed undiminished to every portion of the fluid and walls
Term
 Pressure in a Hydraulic System
Definition
 P1=P2 F1/A1=F2/A2
Term
 Volume in a Hydraulic System
Definition
 V1=V2 A1d1=A2d2: where d is the displacement
Term
 Work Done in a Hydraulic System
Definition
Term
 How far will an object sink in a fluid?
Definition
 Weight of the fluid displaced (buoyant force) is less than the object's weight: Object will sink Weight of the fluid displaced (buoyant force) is more than the object's weight: Object will float
Term
