Abstract
A class of incompressible fluids whose viscosities depend on the pressure and the shear rate is considered. The existence of weak solutions for flows of such fluids under different settings was studied lately.
In this short note, twe recent existence results are adverted and their direct generalization into different setting is indicated; in this setting the corresponding energy estimates are derived showing the existence of a solution to an approximate system.
