Processing non-Newtonian Products: Determining the Pressure Drop for a Power-law Fluid along a Straight Circular Pipe

This application note demonstrates how formulae can be used to calculate pressure requirements for pumping fluid over long distances, the selection of optimum pump diameter as well as measurement and control of flow rate. In this example, power-law analysis is used to determine the shear rate value and the pressure drop across the pipe for transportation of a shampoo product. These values can be used to predict pressure requirements for achieving the required flow rate in a straight circular pipe.
