For my master's degree project, i need to develop a simply hydraulic circuit to comand a cutter or a lathe.
For the first part, i'm using steel pipe, so I don't have problems.
For the last part, I need to use and hose pipe in pvc+steel mesh. The problem is that Amesim need a unique bulk modulus for a pipe, and I really don't know where to find this parameter for a pipe composed by more element like pvc and steel.
Thanks a lot.
Usually these values are provided by suppliers and can be found on catalogs.
Referring to the Amesim help of the hose component:
The value of the effective bulk modulus depends on the pressure inside the hose. Typical values could be:
I hope it helps,
Thanks For the advice, federico (sei italiano??)
Unfotunatley, no suppliers provide this value because it's considered not relevant for the customers, for the choice of the hose ( or maybe, this is the answer of all the suppliers i asked that). I didn't found it in any catalogue
