Thanks Joshua for your prompt reply. Now its clear for points 1 & 3 2) If its point of resolution of forces, it should have been at the interface of nozzle and equipment vessel connection or at the end of flange (where it connects to external piping). Since allowable forces on nozzles are specified at the end of nozzle(generally). So the resolution point should be different (multiple resolution points for each nozzle) for all the nozzle connections of rotating equipment. 4) But what is pedestral axis, is it related to base plate or mounting plate orientation of equipment? Meanwhile for user defined rotary equipment how to decide the pedestral axis.
