How can I include pulsation forces from piston type pump to piping?
Answer: (from Karim Rinawi)
The best way is to simulate the acoustic model using Bentley PULS. It will calculate the shaking forces and can export these using harmonic HMF file.
Otherwise you would need to assume some pipe harmonic forces at elbows. Sometimes you need to change the load frequency to match pipe resonance for worst scenario.
