  I discuss a correspondence between a fictitious fluid in the black hole
membrane paradigm and highly excited closed string states according to the
black hole correspondence principle. I calculate the membrane transport
coefficients of an electric NS-NS 2-charged black hole and transport
coefficients of the highly excited closed string states which possess a
Kaluza-Klein number and a winding number. Comparing both the transport
coefficients at the correspondence point, I show that, except for the bulk
viscosity, the membrane transport coefficients are of the same order as the
transport coefficients of the closed string states on the stretched horizon.
Also, I show that, except for the bulk viscosity, both the dimensionless
transport coefficients, which are defined by dividing the transport
coefficients by the entropy density, are exactly equal if the central charge is
6.
