What is the maximum allowable pressure for MR fluid?
A. Operation under high pressure is not a problem. In fact, we have operated MR fluids at static pressures up to 2500 PSI (17 MPa). The fluids should be fine at pressures at least an order of magnitude greater than this. However, at these pressures one will need to take into account the bulk compressibility, which will increase the effective volume fraction.
