The submarine's wake

ORAL

Abstract

An object moving under water creates a wake at the surface. We mesure the amplitude of the wake and the additive drag it creates on a sphere moving horizontally at different dephts an speeds. We isolate two different comportements at high and low depht. Can we deduce the size and depht of a submarine from it's wake?
