During a pilot test, a Non-Newtonian fluid flows in a horizontal 37 mm ID pipe. The pressure drop per length is measured to be 917 Pa/m and it is experimentally determined that the Shear stress () [Pa] and Shear rate () [s-1] are related by the following equation:

Estimate the average linear velocity (m/s), volumetric flow rate (m3/s) and the pressure drop per length for the same experimental fluid when flowing in an industrial scale pipe of 180mm ID with the same wall shear stress.

1. identify, define and analyse the problem (identifying given information and other relevant sources of information that can be used to solve the problem) 2. Strategy to solve the problem (Outline your strategy to solve the problem giving equations where necessary and applicable principles and laws what other strategies could have been used?) 3. Implementation of strategy 4. Assumptions and their limitations (state your assumptions, analyse essential or critical assumptions and limitations and justify your procedures) 5. Solution analyses
