1. Bernoulli's principle

v	fluid flow speed at a point on a streamline (m/s)
g	acceleration due to gravity (m/s²)
z	elevation of the point above a reference plane, with the positive z-direction pointing upward – so in the direction opposite to the gravitational acceleration (m)
p	pressure at the chosen point (N/m²)
ρ	density of the fluid at all points in the fluid (kg/m³)
constant	constant (m²/s²)

2. Bernoulli’s Equation (conservation of energy)

P₁	Absolute pressure at point 1 (N/m²)
ρ	Fluid density (kg/m³)
v₁	Velocity of the fluid at point 1 (fluid flow speed) (m/s)
g	Standard gravity
h₁	Height of point 1 above some reference point (m)
P₂	Absolute pressure at point 2 (N/m²)
v₂	Velocity of the fluid at point 2 (fluid flow speed) (m/s)
h₂	Height of point 2 above some reference point (m)

3. Borda–Carnot equation ( in relation to Bernoulli's principle)

Δ_E	The fluid's mechanical energy loss per unit of fluid volume (J/m³)
p₂	The pressure at location 2 (Pa)
p₁	The pressure at location 1 (Pa)
ρ	The fluid density (kg/m³)
v₂	The mean flow velocity after expansion (m/s)
v₁	The mean flow velocity before expansion (m/s)

5. Tax amortization benefit

FMV	The fair market value of the intangible asset (dimensionless)
VBAB	The value of the intangible asset before amortization benefits (dimensionless)
TAB_factor	TAB factor (the value assuming end-year discounting) (dimensionless)

FMVVBABTAB_factor

6. Tax amortization benefit factor

TAB_factor	TAB factor (the value assuming end-year discounting) (dimensionless)
t	The corporate tax rate applicable to the future amortization of the asset (dimensionless)
n	The tax amortization period of the asset in years (dimensionless)
k	The discount rate (dimensionless)
