Graduate Attribute 2: Application of scientific and engineering knowledge Apply knowledge of mathematics, natural science and engineering sciences to applied engineering procedures, processes, systems and methodologies to solve broadly-defined engineering problems. The following competence indicators are used for the assessment:

1 Ability to apply an appropriate mix of knowledge of mathematics, statistics, natural science and engineering science knowledge at a fundamental level, on the solution of well-defined engineering problems. 2. Ability to use applicable principles and laws when solving problems. 3. Ability to identify and analyse essential or critical assumptions and limitations. 4. Ability to present concepts and ideas in a logical and methodical manner. 5. Ability to outline and justify procedures for dealing with uncertain/undefined/ill-defined variables. 6. Ability to perform work within the boundaries of the practice area You must demonstrate competence in all indicators to be declared competent in both GAs. All compulsory questions must be answered. __________________________________________________________________________________ PROBLEM STATEMENT: Question 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.
