True centrifugal casting is performed horizontally to make large diameter copper tube sections. The tubes have a length = 2.0 m, outside diameter = 0.4 m, and wall thickness = 30 mm. (a) If the rotational speed of the pipe = 600 rev/min, determine the G-factor on the molten metal. (b) Is the rotational speed sufficient to avoid "rain?"
