input WATER HAMMER in static model
input WATER HAMMER in static model
(OP)
Hello,
Please, find attached an example of a piping system. Considering water hammer effect because the valve at node 60.
I want to analize in a static model the pressure effect in my piping system. I consider that the wave return to the pipe and I have to introduce a force in each change of direction. I introduce the force "F" till no more restraint in the same dirección (the force F at node 50 is compensated by the restraint Rx at node 35, the force F at node 40 is compensated by the restraint Ry at node 35 and the force F at node 30 is compensated by the restraint Rz at node 35).
Do you think that is it a correct way to analize the water hammer in a static analysis?
Thanks in advance.

How the forces are distributed between supports depend on rigidity of the pipe between supports.
Independent events are seldomly independent.

Do you mean how the momentum forces are calculated, or if pressure and pressure expansion stresses are included? You haven't said anything about that either.
