A horizontal cylinder closed from one end is rotated with a constant angular velocity `omega` about a vertical axis passing through the open end of the cylinder. The outside air pressure is equal to `p_0`, the temperature to `T`, and the molar mass of air to `M`. find the air pressure as a function of the distance `r` from the rotate axis. The molar mass is assumed to be independent of `r`.
