Dear ones,
Another matter in this connection would be the mass offset due to the actuator (whatever type it may be) with respect to the centre-line of the pipe, its angularity (star valves in catalyst fluidised transfer lines e.g.) with the axis, and things like that. It all depends how one models it in Caesar II, and to what extent, it adapts to the reality.
Cheers!
