To answer this question, we discuss the properties of electronic viscosity in deformed graphene by introducing strain and velocity gradient as pseudo-magnetic and pseudo-electric fields, respectively, into the Dirac model. We found that viscosity decreases with applied strain, simultaneously leading to a rather significant increase of the Reynolds number and enabling a real possibility for manifestation of noticeable turbulent effects in strained graphene.
