- A closed cylindrical tank of 4 m in height and 2 m in diameter contains water to a depth of 3 m. When the cylinder is rotated at a constant angular velocity of 40 rad/s, show that nearly 0.71 m2 of the bottom surface of the tank is uncovered.
- Relevant Equations
- pressure surface, Bernoulli's equation
why is ro = 0.2255?
Thank you
