The experiment is trying to determine how much of a solution containing vitamin C is required to be added to 1 cm3 of blue chemical to change its colour from blue to clear. The experiment users an new and old lemon‚ orange and blackcurrant juice‚ each with varying amounts of vitamin C content. Each experiment has independent and dependent variables. The solutions of soft drinks contain different levels of vitamin C (with old and new varieties) will be the independent variables in the experiment

AMR was allowed to reach steady state conditions. Traditionally‚ steady state conditions are defined as the state when temperature at each thermocouple locations approximately does not change with time. However‚ and due to the limitation of the laboratory‚ and after several experiments found the initial control of the fluid flow rate was a difficult process‚ also the measuring of the actual time variation of the fluid flow rate. Furthermore‚ due to the little mass of fluid flow‚ the experiments didn’t
