Abstract

A method was proposed to determine the snow fraction from the hydraulic gradient of a snow/water mixture flowing in a vertical pipe with a circular cross section. Experimental results showed that the mixing of snow did not affect the frictional force on the vertical pipe wall, and that the volume snow fraction C' in the pipe was nearly equal to the value C at the discharge. Based on these results, it was confirmed that C' was determined within an error of 2% by the method proposed here for the pipe diameter D corresponding to the range of Froude numbers Fr between 5 and 35 [Fr=U_m²/(|1-s|gD), U_m;flow velocity, s;density ratio of ice to water, g;gravity acceleration.
