[University Physics Experiment-2] Measurement of Liquid Viscosity Coefficient

Preface

Recently I am sorting out some materials of courses I have learned. Although some courses have nothing to do with my major, they still need to be learned. After all, most of the current scientific research results come from cross-fields, and what is needed is talents who can think across fields. I also studied it seriously. But I thought for a while, instead of letting them rot in my folder, I might as well share them with everyone (most importantly, I think most of the experimental reports on the Internet have shortcomings, they are not very comfortable to look at, and boast a wave , Haha), of course, I will also share some of my experience and thoughts when doing these homework. Maybe it is not as accurate as the physics major, so everyone should look at it critically.

Here I wrote a few simple lines of code to process the data

Attention! ! ! ! ! Here is a problem with my processing. I should use exponentials when fitting the curve. As a result, I have a hand injury and clicked a straight line. You can re-fit it in Excel with the same data.

Fraud points, haha

Sum up

This report of mine feels a bit more mature than the previous ones. Maybe you don't understand some places, so rest assured that I will write an explanation of error analysis later. In this report, you can see something not only in terms of experimental data analysis, emmm, this is because the teaching assistant told me to reflect your thinking in the report, so I pondered some things. Don’t ask, ask is for volume, for GPA, hee hee
