Abstract: Measured headlosses for potatoes transported in 9.5-inch-diameter horizontal and vertical pipes were compared with mathematically predicted headlosses. Measured and predicted headlosses agreed well when the predictions were made with equations that had been developed for the heterogeneous flow of sand and coal particles. Flow profiles were analyzed for potatoes transported in metal flumes with various cross sections and slopes. Manning roughness coefficient could be estimated with a form of an equation published for the heterogeneous flow of sand. Potato concentrations were varied and potato handling rates were varied from 780 to 1,800 pounds per minute in the trials conducted. Design criteria for pipelines and flumes were developed.
