SUMMARY
The discussion focuses on calculating the pressure distribution in a rotating vertical tube, specifically at a rotation speed of 3000 RPM, with an initial pressure of 1.5 bar at the axis (r=0) and a temperature of 293K. The pressure distribution is derived from balancing the centripetal force and the weight of the fluid element, leading to the conclusion that pressure is a function of both radial (r) and vertical (z) coordinates, expressed as P = P(r,z). The participant seeks assistance in adapting the principles used for horizontal tubes to this vertical configuration.
