This study represents the first comprehensive effort to assess through 1 numerical simulations of the equation of motion of the density matrix, and 2 approximate analytical procedures involving an expansion of the liouville potential, the multiplicative constant associated with the quantum potential as used in quantum hydrodynamic transport. It was found that when quantum effects are corrections to classical calculations, as in NN-N structures the factor 13 is a satisfactory multiplicative constant. When the quantum potential is no longer constant but is position dependent and less than unity.
