This paper consists of the research that had been done based on this chosen topic, Development Length for Non-Newtonian Laminar Flow in Circular Pipe. The application of the information gained from this research can benefit various industries handling and utilizing Non-Newtonian Fluid. The objective of this project is to study the development length requirement of a non-Newtonian fluid via experimental measurements. The requirement for this experiment is that, the literature reviews for development length of non-Newtonian fluid through a circular pipe was mostly on analytical and numerical analysis. With that the scope for the experiment will only be within laminar regime with non-Newtonian fluid in order to investigate the development length. In the early stages a flow loop design was proposed for the project in order to carry out the experiments. The design of the flow loop was proposed and adapted from Dr. Azuraien bt Jaafar flow loop in Liverpool, UK which was used for her degree of Doctor in Philosophy. The test section for the flow loop however was designed using ASME 831.3 standard taking into account the operating pressure, possible erosion by designing the appropriate thickness. The pressure tapping part at the test section design was taken from an already available design at the block IS-laboratory. Experiment was designed with pre-set conditions in accordance to the available pump at our disposal. Certain parameters like pressure and volume flow rate are fixed. Using the completed flow loop, the experiment was done using 5 different samples (UTP Tap water, Xanthan Gum solution 0.02wt %, 0.03wt %, 0.04wt% and 0.05wt %) in which the results have been analyzed. The findings from the experiments were that the development length for non-Newtonian is slightly shorter than Newtonian fluids.
