Abstract

The performance characteristics of an eccentric venturimeter with elongated throat for 68 mm NB pipeline having an area ratio of 0.327 for the measurement of flow rates in solid-liquid flow, have been investigated. The modified geometry of the venturimeter is expected to suppress the erosion rate caused by the motion of solid particles. Copper tailings obtained from a processing plant have been used with water to prepare the solid-liquid mixture. Experiments performed over a wide range of flow velocities and solid concentrations show that the value of discharge coefficient of the eccentric venturimeter with elongated throat is slightly higher for slurry flow as compared to the value obtained for clear water flow. It is also seen that the average value of discharge coefficient obtained at different solid concentrations increases marginally with increase in solid concentration. The redistribution of solids at the throat of the venturimeter has also been investigated at different solid concentrations.
