Continuity equation
ρAV = ρ’A’V’
ρAV = ρ’A’V’
Continuity equation
Bernoulli’s Equation
P+0.5ρV^2 =P’+0.5* ρ*V’^2=Po
P+0.5ρV^2 =P’+0.5* ρ*V’^2=Po
Bernoulli’s Equation
What does the equation ΔP=0.5ρV^2 demonstrate?
static pressure is always equal to dynamic pressure
What are the two fluid flow types?
Compressible and Incompressible
Compressible Flow
Flow in which the density of a fluid can change from point to point
Incompressible Flow
Flow in which the density of a fluid remains constant
Flow in which the density of a fluid remains constant
Incompressible Flow
