	number = {6134950},
	year = {2000},
	month = {oct},
	abstract = {A method and apparatus including programmed computers are provided for determining the viscosity of a first stream in a laminar flow and a second stream in a laminar flow, the flow rates, the centerline of the flow channel, and the position of the interface between the streams with respect to the centerline, and for calculating viscosity ratio of the first stream to the second.},
