Abstract

The paper deals with the effect of the parameters of aqueous slurries of particulate matter on the functional relationship between the specific energy and the flow rate of hydrodynamic dredge pumps. The empirical conversion equations available from literature are reviewed. The methods of converting the pump characteristics at clear water to those which apply for slurries have been incorporated into a straightforward, user-friendly computer program which can be run on a PC. The program may be adopted in the design of hydro-transportation systems involving hydrodynamic dredge pumps. The program computes the specific pump energy as a function of flow rate at given rotary speed, for specific operating conditions of the pump, i.e., for specific parameters of the slurry.The paper deals with the effect of the parameters of aqueous slurries of particulate matter on the functional relationship between the specific energy and the flow rate of hydrodynamic dredge pumps.
