SUMMARY

The discussion focuses on calculating the force produced by flowing water using the equation F = Apv², where F represents force, A is the surface area, p is the density of water, and v is the velocity of water. Participants emphasize the importance of understanding the relationship between these variables to accurately compute the force. The conversation highlights the relevance of basic physics principles in practical applications involving fluid dynamics.

PREREQUISITES
  • Understanding of basic physics concepts, particularly fluid dynamics.
  • Familiarity with the equation of motion and momentum.
  • Knowledge of water density and its typical values.
  • Ability to perform calculations involving area and velocity.
NEXT STEPS
  • Research fluid dynamics principles, focusing on Bernoulli's equation.
  • Learn about the impact of surface area on fluid force calculations.
  • Explore the relationship between velocity and force in fluid flow.
  • Study real-world applications of force calculations in hydraulic systems.
USEFUL FOR

Students in physics, engineers working with fluid systems, and anyone interested in understanding the mechanics of water flow and its force calculations.

So let's say you have water flowing at a given speed.
Ballpark, how much force can be produced with a given surface area?

It should be easy, but I've managed to fail physics over and over.
Good with math though. Relevant equations would make me extremely happy.

Hi Locust! :smile:

mass = density times volume :wink:

force = rate of change of momentum :smile:

enjoy! :-p
 
The force acting on the water can be calculated
F = Apv2

where A- area
p-density of water.
v- velocity of water.
