Improving the water flow in pipelines using floating technique

Pipelines transportation is widely used regardless in any industry.Mostly,liquid and gases are sent using the transportation method through a pipe.Turbulent flow in pipeline causes friction drag and pressure drag which results in pressure drop and increases the operational cost by increasing the pum...
