使用Tracker引流液体的家庭实验室
Lab at Home of fluid draining with Tracker
摘要：
由SARS-CoV-2病毒引起的大流行已经威胁到学校和大学的面对面教学活动。从面对面的课程到在线活动的转变使活动产生了效率低下的结果。特别是，一个关键问题是在不进入实验室的情况下组织实验室活动。本文提出了如何通过让学生在家中进行流体的排泄物理实验来克服这一问题。换句话说，使用家中常见的设备或可以低价购买的设备实际上是合理的。本文对液体从容器孔中排出的过程进行了实验研究。从分析步骤开始，我们引入了一个免费的视频分析软件Tracker，以获得准确的结果。有趣的是，我们观察到粘度的影响导致液体排水时间的延迟。我们的研究表明，容器的开放空间半径与孔半径之比$\sqrtλ$可用于确定排水时间。
英文摘要：
The pandemic caused by the SARS-CoV-2 virus has threaten the face-to-face teaching activity in both schools and universities. The transformation from face-to-face classes to online activities yielded inefficient outcomes from the activities. Particularly, a key issue was organizing laboratory activities without accessing the labs. In this paper, we propose how to overcome this problem by enabling the students to perform physics experiments of fluid draining at home. In other words, the use of equipment commonly available at home or that can be purchased at a low price is practically plausible. In the present work, we do an experimental investigation of liquid draining through a hole of a container. From an analyzing step, we introduce a freely-accessible video analysis software, Tracker, to obtain accurate results. Interestingly, we observe the effects of viscosity causing a delay of draining time of liquids. Our study shows that a ratio of open-space radius of the container to the hole radius, $\sqrtλ$, can be used to determine a draining time.
