Introduction

The video presents an overview of Problem 6 from the IYPT 2025, focusing on the dripping patterns of a leaky faucet. The presenter aims to investigate how these patterns depend on various parameters, including flow rate and nozzle characteristics. Introduction

Preliminary Analysis

The initial experimental setup involved a bathroom faucet, but challenges such as inconsistent flow rates led to the development of a more controlled setup. This included a large tank, a controlled valve, and an electronic scale for accurate flow rate measurement. Preliminary Analysis

Theoretical Investigation

The presenter explains the dripping phenomenon, highlighting the balance between gravitational force and surface tension. A simplified model is proposed to understand the time between drops, though it overlooks complexities like residual water at the nozzle tip. Theoretical Investigation

Period Doubling

At higher flow rates, the time between drops exhibits period doubling due to oscillations in the residual water. This section explains how the phase of oscillation affects the timing of droplet detachment. Period Doubling

Varying Parameters

The impact of varying the nozzle diameter on the time between drops is discussed, noting that larger diameters lead to longer intervals due to increased critical volume for droplet formation. Varying Parameters
