Thanks for all of your responses, I guess I think thinking of the question more in terms of energy balance.
For the case of a wind mill: The propeller disk sweeps out a certain circular area A. The air moving past it has density and speed. Given these, one can estimate the maximum potential...
I have been thinking about how to optimize number of blades for a given propeller application. I realize there are many applications for them so let me narrow this down somewhat.
Case 1:
Most of the large electrical wind turbine generators have three blades. This number is arrived at...
Hello all,
When I am solving a thermodynamics (energy of compressed gas/liquid) problem, which cases should I use Enthalpy and which cases for Internal Energy? It has been 11 years since I took thermodynamics and I don't remember which one should be used.
Things I do remember: The Internal...
