Kinematic pressure
= Kinematic pressure
{title2=$p/\rho_0$}
Dividing a <pressure> disturbance by the constant reference <mass density> $\rho_0$ gives a quantity whose <gradient> enters the <Boussinesq equations> directly as an <acceleration>. Its units are squared <velocity>. Distinguish this convention from physical <pressure> when calculating <energy flux> or comparing <wave polarization> formulae.
