    164164The table starts rotating for the first time with a velocity of 50 rounds/ sec. It gets slowly filled with water to a level of 60 cm. This takes about 3h. Before we can start the experiments, the lasers first have to be adjusted. To check how long the water stays in the water, we conduct a little experiments with water (from the tank) that is enriched with particles. After about 2 hours a 4 mm thick clear surface layer develops.

    166 After filling the tank Thoma measured the water level to be  point where water level does not change with rotation 60.4 cm  Center of tank – 42.5 + 16 cm = 58.5 cm Tank wall (6.5 m) – 62.4 cm

    168 Particle sedimentation test Water was taken from the tank, mixed with particles (+ wetting agent) and set to settle in a glass “vase” with a narrow (ca 3cm) and tall (ca 10 cm) neck. The upper level with particles were observed as follows:
