Jet length
= Jet length
{title2=$L_J$}
For source kinematic <momentum flux> $m_0$ and <buoyancy flux> $f_0>0$, <dimensional analysis> gives $L_J=m_0^{3/4}/f_0^{1/2}$. Under constant <Batchelor entrainment>, the actual turning length also contains an <entrainment coefficient> factor of order $\alpha^{-1/2}$.
