1. A closed vertical cylindrical vessel, 1.50m in diameter, 3.60m high is 7/10 full of liquid (SG=1.30) and is revolved about its vertical axis with a constant angular speed. The air inside the vessel is 105 kPa. a. Determine the angular speed in revolution per minute necessary to set the vertex of the liquid surface 0.75m above the bottom of the vessel. b. What is the maximum pressure at the bottom of the tank during rotation? c What angular speed in rad/s will just zero the depth of the liquid at the center of the vessel? d. If the angular speed is 200 rev/min, determine the diameter of the portion free of liquid at the bottom of the vessel.
