Investigating the Torricelli Law Using a Pressure Sensor with the Arduino and MakerPlot
Atkin, Keith
Physics Education, v53 n6 Article 065001 Nov 2018
This paper examines the Torricelli law for the flow of liquid from a small drain hole in a container. It shows how the system can be modelled using either a traditional calculus-based approach or a non-calculus step-wise computer method appropriate to the background of the student group. An experiment to measure the head of out-flowing liquid as a function of time is then described. The conventional method of manual timing is replaced by a pressure-sensing technique involving use of the Arduino microcontroller and MakerPlot graphing software.
