On reconnait ici le même dispositif que celui utilisé pour les mesures dans l'air (sous un autogire), comme sur cette image :
Du fait de la plus forte Viscosité cinématique de l'eau, le Reynolds obtenu par remorquage d'une sphère dans l'eau est 14,3 fois plus fort que celui obtenu dans l'air (à vitesse et diamètre égaux).
