From the earliest study of hydromechanics it has been assumed that the reaction between a stagnant fluid and body moving through it is the same as for the fluid passing the fixed body with the same relative motion. So many experiments however seemed to disprove the assumption that at one time some prominent investigators question its validity. This report further investigates the horizontal buoyancy in wind tunnels.
