Hi,

I am trying model source for my uds which is given by the equation as in fig attached. Where a, kc, kmu are constants. H is the concentration or uds and $\dot{\gamma}$ is the shear rate.

I find it difficult as there are first derivative and second derivatives of shear rate. If anyone can help me out with it will be grateful.

Thanks and regards
