Bulk modulus for silicon based hydraulic fluid

Bulk modulus for silicon based hydraulic fluid

(OP)
Can anyone help me find a ball park number for the bulk modulus of a silicon based hydraulic fluid, Ximeter 200.

An engineer wants to put it in a cyclic damper at 1Hz with no accumulator and I need to determine the pressure increase with temperature.

It should be around 100kPa if I am lucky. I just cannot find the information anywhere.

Some data here: (ain't google cool?)

You'll need to ballpark your fluid viscosity, but I'd guess you have something around 100 centistokes (cs) plus or minus 50, for a hydraulic fluid...luckily the curves flatten out above a few cs. Temperature effects may be trickier to pin down.
