mechanical engineering - Why is my Venturi pump much .

begingroup (1) Indeed 128m/s (according to my calculations) should lift the water 1 meter high, therefore I reasoned that the 60m/s I managed to achieve should at least have noticeable lifting, not the meager results I've got. (2) Huh. To be honest I thought that the fast air flow is still very close to the straw orifice, and I used a 16 mm hose so that the water have enough space to flow.
