The liquor is pumped through a large nozzle and the velocity head is utilized to draw the gases to be absorbed into the liquid .

Unfortunately, the trim exit velocity head alone is not a good predictor of such animportant phenomena.

This example demonstrates that a low trim exit velocity head does not result in a low noise level in the valve, unless the valve outlet mach number is low.
