SUMMARY

The discussion focuses on predicting the time it takes for water to drain from a cup, emphasizing two critical variables: the height of the water and the size of the hole at the bottom of the cup. Participants noted that while the flow rate is influenced by these factors, the total drainage time also depends on the volume of water. The need for accurate data collection was highlighted, as incorrect data can lead to flawed predictions. A formula or method for calculating drainage time was sought by the original poster.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with basic mathematical modeling
  • Knowledge of variables affecting fluid flow
  • Experience with data collection and analysis techniques
NEXT STEPS
  • Research the Torricelli's Law for fluid drainage
  • Explore mathematical modeling techniques for fluid dynamics
  • Learn about the impact of hole size on flow rate
  • Investigate methods for accurate data collection in experiments
USEFUL FOR

Students in physics or engineering, researchers in fluid dynamics, and anyone interested in experimental design related to fluid flow and drainage processes.

Hey,

To start off, we are supposed to be able to predict how long it will take for water to drain from a specific cup. There are 2 variables in this, the height of the water in the cup (not volume), and the size of the hole in the bottom of the cup.

The data I collected appears to be incorrect and I don't no if ill have another chance to collect data. What I basically wanted to know is either a way to go about solving this problem, or if there was a formula for this.

Thanks

The rate of flow depends on the height of the water in the cup and the size of the hole in the bottom of the cup. But the time it will take for water to drain from a specific cup depends on the volume along with the other variables.
