Homework Help Overview

The discussion revolves around a problem involving turbines and windmills, specifically comparing the moving speed of air molecules under different conditions involving reversed and movable windmills. The original poster presents a scenario that includes both reversed steady windmills and movable windmills, while also referencing various equations related to motion and energy.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the terminology used by the original poster, particularly the terms "reversed steady windmills" and "movable reversed windmills." There is an attempt to clarify the context and meaning of these terms, as well as the relevance of the provided equations to the problem at hand.

Discussion Status

The discussion is currently seeking clarification on the problem's terminology and context. Some participants suggest that the original poster consult their professor for further guidance, indicating that the terminology may not be widely understood. There is a recognition that more information is needed to provide meaningful assistance.

Contextual Notes

Homework Statement


Consider a turbine which actuates the windmills by blowing air into it. (If we use beat steady windmills (which is called reverse windmills) instead of movable windmills, deliberate the following conditions by parametric view. (Ignore the friction power (force))
A. Compare moving speed of air molecules in the following conditions:
1. There are reversed steady windmills between movable windmills.
2. There are movable reversed windmills in the middle of movable windmills which are actuated by wind power (energy).

Homework Equations


I am not sure
E = ½mv2
W = Fd
mv22 = ½mv12
v2 = v02 + 2as
a = ( v2 - v02 ) / 2s
F = ma = m ( v2 - v02 ) / 2s
K = 0.5mv2
Wtot = K2 - K1 = ΔK

Can you ask your professor for some clarification or guidance in the right direction?

Can you shed any light on what these terms mean? I can find no matches in a Google search.

Edit: that wasn't quite true. I got lots of matches on "reverse windmill", as a particularly flamboyant way to score in basketball.

I just meant that it appears that you don't know where to start - your description is vague, then you have several formulas that have to do with motion and force and kinetic energy.

So far, nobody here is familiar with this particular terminology, so I thought a fellow classmate or your prof might be able to shed more light that we can (right now, at least).

This forum is great for helping you along in the right direction, but we need to understand more about this problem before we can do that.
