My working copy let's you do this:
sage: var('Re')
Re
sage: f = 0.25 / (log(5.74 /Re^0.9, 10))^2 / 4
sage: f._eval_self(CC)
0.331368631904900/log(5.74000000000000/Re^0.900000000000000)^2
I'll try to submit this patch for review in a couple of days. If you
want it sooner, replacing the else clause in
sage.symbolic.expression.Expression._self_eval with
return new_Expression_from_GEx(self._parent, res)
should get you the same functionality.
Cheers,
Burcin
