SUMMARY

The discussion centers on comparing the water flow and pressure differences between tap water, fire hoses, and pressure washers. It emphasizes the importance of estimating the diameter of the water stream and the volume of water moved per second to calculate the speed of the water. By applying the definitions of kinetic energy and power, users can derive meaningful insights into the performance of each water source. This analysis provides a foundational understanding of how water pressure and flow rate impact cleaning efficiency.

PREREQUISITES
  • Basic understanding of fluid dynamics
  • Knowledge of kinetic energy and power equations
  • Familiarity with measuring flow rates
  • Concept of water pressure and its implications
NEXT STEPS
  • Research how to calculate flow rate using diameter and velocity
  • Explore the physics of kinetic energy in fluid systems
  • Learn about the specifications and applications of pressure washers
  • Investigate the differences in water pressure between various hoses
USEFUL FOR

This discussion is beneficial for engineers, cleaning professionals, and anyone interested in understanding the efficiency of different water delivery systems for cleaning and maintenance tasks.

Okay, so I don ' t have any real specs but i just want to know how big is the difference between water from tap versus the one from fire hose versus the pressure washer?

You can get started on this calculation on your own. Make reasonable estimates of the diameter of the stream and how much water is moved per second; from that you can get the speed of the water in the stream. Now you can use the definitions of kinetic energy and power to get answers about as good as your original estimates.
