 Define density
 Mass/volume

Define specific gravity
S.G.= Density(substance)/Density(water)

What is the density of water

Define pressure and units

Give equation for the pressure of a fluid at rest with uniform density in a sealed contatiner
 P=(density)by
 Y=depth of fluid

What is P of the atmosphere in standard units
101,000 pascals

Describe pascals principal
Pressure applied anywhere to an enclosed incompressible fluid will be distributed undiminished throughout that fluid

What kind of machine utilizes pascals principal
Hydraulic lift

Describe archimede's principle
The bouyant force is an upward force acting on a submerged object, and is equal to the weight of the fluid displaced by the submerged object.

What is the bouyant force equation
 Fb=fluid(density)Vg
 In other words, the bouyant force is equal to the weight of the fluid that was displaced. Archimedes principle

What are the two types of motion in fluids with motion and what is their role
 1: random translational motion: contributes to fluid pressure at rest (motion of molecules)
 2: uniform translational motion: shared equally by all molecules at a given location. (Motion of flow)

Define the characteristics that make up an ideal fluid
 1: no viscosity
 2: incompressible
 3: lacks turbulence

Describe and Define the continuity equation
 Rate of flow of a fluid
 Q=Av
 An is cross sectional area
 V is velocity
 Q is volume flow rate

Whats is the equation for mass flow rate
Multiply volume flow rate (Q) by density

Describe and define Bernoulli's equation
 P+(density)gh+(1/2)(density)v^2=K
 K is a fluid specific constant

Define stress and strain
 Stress=F/A
 Strain= Dimension/original dimension

Describe and define modulus of elasticity
 A proportionality between stress and strain which can be thought of like Hess's law
 Stress/strain or how much stress can a systems strain handle before breaking

Describe and define the three types of modulus
 1: Young's modulus (E)= tensile strength
 2: Shear modulus (G)= shear stress
 3: bulk modulus (B)= compression and expansion

Give the equation for the velocity of a fluid in motion
V=sqrt(2gh)
