1. A pipe 2.50 cm in diameter is 1.0 m long and filled with 0.60 m of water. If the pipe is capped at both ends and rotated in a horizontal plane about a vertical axis through one end of the pipe, what is the pressure at the other end of the pipe when it is rotating at 200 RPM?

Please provide solutions.

Problem A: An open vertical cylindrical tank 0.60 m in diameter and 1.20 m high is half full of water. If it is rotated about its vertical axis so that the water just reach the top, find the speed of rotation. What will then be the maximum pressure in the tank? If the water were 1.0 m deep, what speed will cause the water to just reach the top? What is the depth of the water at the center?

2. If the tank of Prob. A is half full of oil (sp. gr. 0.75) what speed of rotation is necessary to expose one-half of the bottom diameter? How much oil is lost in attaining this speed?

Answer: 18.70 rad/s ; 42.5 litres
