1     It is important that you carefully read through the Information for Virtual Lab 3 – Modelling before you carry out the virtual lab experiment. This will make it easier for you to perform the experiment, leading to better learning experience and maximum learning outcome. You should also understand the specific reporting requirements for this lab before writing up your report. Participation in this virtual laboratory experiment and timely submission of laboratory reports are compulsory. Laboratory reports must be submitted through Turnitin on Canvas by the specified deadline. The specific due date and time for report submission will be announced on Canvas when the virtual lab experiment is open for access. Laboratory reports submitted after the due date will be penalized at the rate specified in the Unit of Study Information. On the following pages you will find: Introduction Experimental Platform and Procedures Guide for Lab Reports Assignment/Report Cover Sheet
2     Introduction Aim This experiment is conducted in a virtual environment, which simulates a scenario of a ball being suspended by an upward jet of fluid. The purpose of the virtual lab is to determine the dependence of the ball suspension height on the properties of the ball, the fluid medium and the jet flow rate. This lab aims to enhance your understanding of dimensional analysis, modelling and similitude, and their applications. Tasks 1. Carry out dimensional analysis to obtain a set of dimensionless parameters ( i.e. the  groups) to describe the problem. Either the ‘ Trial and Error ’ approach or the Buckingham Theorem procedures may be adopted. Note that different groups may be formed. 2. Design a set of experiments for quantifying the dependence of the dimensionless ball suspension height on the other groups. When designing experiments, only vary one group at a time and maintain the other groups constant. You will need to experiment with at least 5 different values for each of the independent π groups. This may be achieved by the combination of different ball and jet flow parameters. Sometimes, especially in real physical lab experiments, the limited choices of experimental balls and other constraints may make it difficult to maintain all the other groups constant. In that case, you need to carefully design the experiments to minimize the variations of the other groups. If the variation of the other groups are relatively small, you may treat them as approximately constant. This will contribute to the experimental errors. 3. Conduct the experiments on the virtual platform by choosing different ball size and mass, different fluids (air or water) and different jet flow rates, and record the ball suspension height under each setting.
