Discover the Surprising Power of Water: Tap vs. Fire Hose vs. Pressure Washer

AI Thread Summary
The discussion explores the differences in water flow and pressure between a tap, a fire hose, and a pressure washer. Users are encouraged to estimate the diameter of the water streams and the volume of water moved per second to calculate the speed of the water. By applying the concepts of kinetic energy and power, participants can derive meaningful comparisons between the three sources. The conversation emphasizes the importance of reasonable estimates for accurate calculations. Understanding these differences can highlight the surprising power of water in various applications.

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.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
