Formulation of natural drag-reducing agent from malabar spinach for aqueous liquid flowing in turbulent mode through pipelines

In this study, the drag-reducing properties of mucilage extracted from the stem of the Malabar spinach in both aqueous liquids flowing in pipelines are investigated. Fluid flowing in turbulent through pipelines produce pressure drop as a result of friction resistance. Pumps are installed to reduce p...
