You did not give enough information.
Are you using explicit or implicit solvent?
With implicit solvent you can use Stokes law to estimate the value.
But Gromacs does not come with an implicit solvent force field.
Any explicit solvent force field will give completely wrong results
if you just leave out the solvent.
