# IB Physics HL IA (23/24) (Examiner 코멘트 있음): How accurately can the viscosity coefficient of water (η) be investigated by observing the effect which varying distance between two capillary tubes have on the height difference of water, provided the constant flow rate of water?

View Junjujun916's Full Store본 문서는 2020년에 작성된 Physics HL IA이고 점수는 23/24점을 받았습니다. 주제는 Poiseuille’s Law에 관한 실험이었고 HL인만큼 책에 나오지 않는 내용을 응용하셔 고득점을 받았습니다. 문서에 Examiner 코멘트도 있으니 작성하실때 참고하시면 굉장히 도움이 많이 되실듯 합니다.

**Investigating the Poiseuille’s Law**

**Research Question:** How accurately can the viscosity coefficient of water (η) be investigated by observing the effect which varying distance between two capillary tubes have on the height difference of water, provided the constant flow rate of water?

**Introduction**

Although the Poiseuille’s law is something which I haven’t studied as a part of my syllabus, I have decided to investigate this topic due to its significance in various real-life situations. From the pressure of water used in our house to the blood pressure in cardiovascular system, the Poiseuille’s law is applicable to multiple fields in our life. Personally, I was deeply interested to study further about the mechanism of the arterial blood pressure which drives the flow of blood through all parts of the body due to brief interesting facts about the heart told by my uncle who is a cardiologist. These facts at once captured my attention, and with further research, I was able to understand the , namely the Poiseuille’s law.

The experimental physics project projected itself as an ideal opportunity to explore the topic further and to conduct the experiment for investigating the Poiseuille’s law. As such, my physics IA was focused on the following research question:
