The paper presents results of studies on ice slurry flows through horizontal tubes. The possibility of treating rheological parameters of ice slurry as being those of a kind of Bingham fluid was confirmed. The values of parameters (mass fraction, flow velocity) corresponding to laminar, intermediate and turbulent flow, were determined. This permits to optimize the flow in the systems working with ice slurries. The work includes a comparison of experimental results with computational methods of determining pressure drops for a Bingham fluid over laminar (the Hedstrom method) and turbulent (the Tomita method) ranges. A verification, based on author's experimental results, of the Fanning and Blasius expression for the Fanning friction factor of ice slurry became possible by introducing the dimensionless generalised Reynolds number. In the last part of the paper the issues connected with the criteria for transition of ice slurry from laminar to turbulent flow are discussed.
