Additional experiment:oil viscosity

圖片
Following the success of first experiment, here we advance our story with another experiment by testing the oil viscosity using syringe. Using the well developed model: Poiseuille's Law, we can make use of the fact that viscosity of a fluid is proportional to time taken for it to travel through a given distance. Here we measure the time as the time needed for the oil inside a 10ml syringe to completely drained under the pressure of 50g weight. Since the other parameters such as syringe outlet radius are unobtainable, we measure and compare the time taken as a qualitative comparison as long as control variables are well fixed. Result: Time taken\Oil age t=0 t=5 mins t=10 mins t=15 mins t=20 mins Trial 1 14.2 15.4 16.3 18.1 19.6 Trial 2 14.5 15.3 16.1 18.2 19.8 Trial 3 14.3 15.6 16.3 18.2 20.1 Two sample t-test is used to test significance between t=0 group and t=20 mins group Group\Quantity p-value t-statisitcs stan...

First experimental result

圖片
In our first experiment we had two different trial sections.  In our trial experiment, we followed the procedure that we had initially made. Using a potato cube of 5mm each side. But we quickly found out that this will not work. Our potato cube size was too small and the heat of oil at 200C was too hot. Before the timer reached 2 minutes, all our potatoes had turned black. First trial Quantity\Drop at t=0 t=5 mins t=10 mins t=15 mins t=20 mins Mass before (g) 20.2 20.4 20.1 20.2 19.9 Mass after (g) 6.6 6.9 6.9 7.1 7.3 Mass drop (%) 67.32 66.17 65.67 64.85 63.31 Normalized water out(%) 67.59 67.59 67.59 67.59 67.59 Attached mass(%) 0.27 1.42 1.92 2.74 4.28 Second trial Quantity\Drop at t=0 t=5 mins t=10 mins ...
