To correctly model air cooler,one must understand the equipment. The bundle normally can move if the piping force is high enough. What I did is modelling bundles together with piping system.Input weight of bundle and support friction. If piping is rigid, bundle will move therefore nozzle loading can be reduced. If piping is flexable, bundle not move, and the nozzle loading will be below allowables.
