  The Hawking radiation from the three dimensional rotating acoustic black hole
is considered from the viewpoint of anomaly cancellation method initiated by
Robinson and Wilczek. Quantum field near the horizon is effectively described
by two dimensional charged field with a charge identified as the angular
momentum m. The fluxes of charge and energy are obtained from the anomaly
cancellation condition and regularity at the horizon, and are shown to match
with those of the two dimensional black body radiation at the Hawking
temperature.
