I'ts easy really;  Apply the average damage the waterjet would normally inflict; double it for knockback purposes only, and apply to the vehicles loaded weight.  The number of hexes of knockback is equal to 2mph/yard of knockback produced.  I would divide effective loaded weight by 5 for 'moving on a level surface' for purposes of the calculation.
