'Consider a hose without a nozzle. If you just turn the water on, a large amount of water comes out slowly. There's your low notes on the tuba. Now, all else held constant, put your thumb over 2/3 of the hose and what happens? Less water comes out more quickly.'

All else held constant, the SAME VOLUME of water would pass through 1/3 the gap resulting in the increased velocity.

In practice of course we do use less air as we ascend pitch on our instruments...
