  A perfect fluid is quantized by the canonical method. The constraints are
found and this allows the Dirac brackets to be calculated. Replacing the Dirac
brackets with quantum commutators formally quantizes the system. There is a
momentum operator in the denominator of some coordinate quantum commutators. It
is shown that it is possible to multiply throughout by this momentum operator.
Factor ordering differences can result in a viscosity term. The resulting
quantum commutator algebra is \vspace{1.0truein}
