Click For Summary
To calculate the force produced by flowing water, the relevant equation is F = Apv², where F is force, A is the surface area, p is the density of water, and v is the velocity of the water. The mass of the water can be determined using the equation mass = density times volume. Understanding these equations is crucial for applying physics concepts to real-world scenarios. The discussion highlights the importance of these formulas for calculating the impact of water flow. Mastery of these principles can help overcome challenges in physics.

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.
 
For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
