Definition

relation between heat transferred by a flow and its kinetic energy, expressed by

$K_{Q} = Φ / (v^{3} l^{2} ρ)$ ; where

$Φ$ :: is heat flow rate (ISO 80000-5: Thermodynamics),

$v$ :: is characteristic speed (ISO 80000-3: Space and time),

$l$ :: is characteristic length (ISO 80000-3: Space and time), and

$ρ$ :: is mass density (ISO 80000-4: Mechanics)
