I am studying the skirt thickness for a vertical vessel,,, after facing a corrosion in the skirt support,,,
We need to analysis what is the minimum thickness for the skirt...

Since the PVelite doesn't calculate the required thickness of the skirt a trial and error iterations were done until i get the required thickness,,,

My question is what analysis is the PVelite used for skirt calculation???
and for nozzle forces shall additional separate forces added or the forces add to the nozzle under local stress analysis is enough??
