Triangular-profile wall line plume
= Triangular-profile wall line plume
In a triangular-profile wall line plume, axial velocity and <reduced gravity> decrease linearly from their wall values to zero across the plume width $b$. If the wall speed is $W$, its volume and kinematic momentum fluxes per unit span are $V=bW/2$ and $J=bW^2/3$.
