Lec One :





Fluid Mechanics : Divided by two
groups :





a- Fluid Static deal with Fluid system at rest


b- Fluid Dynamics deal with flowing fluids





Fluid Dynamics : divided into two
groups :





A \ Hydrodynamic





B \ Gas Fluid








Main Units :





Length : meter ( m )


Mass : Kilo gram ( kg )


Time : second & Hour & Minute ( s )


Temp : C


Absolute : Kelvin ( K )








** Fluids Properties





Are the arectetstic pr-passed by fluid that allow for
the determination


Of the fluid behavior with a given systems .





& Specific Weight


& Specific Gravity



& Density


& Pressure


& Bulk Modulus


& Viscosity


& Viscosity Index












Num one : Specific weight


Weight per unit volume = W / V





Where : w= weight ( lb or N )



V= Volume ( ft 3 or m3 )








Num two : Specific Gravity


Specific weight of the fluid divided by the specific
weight of water





S = σ / σ water





S = σ mercury / σ water


= 133 * 1000
/ 9810


= 13.6





Num three : Density ( P )


Mass per unit volume


P = Mass / Volume
or M / V





Where :


P = density


M = mass ( kg
)


V = volume ( m3 )
