I have a question about the minimum amount of heat required to operate a theoretical brayton cycle engine that is optimized for producing shaft power, not thrust (if that matters). What is the relationship between inlet compression ratio and other variables, turbine variables, and minimum...
Good point, but I feel like it is revealing of inner processes that the blades on bratyon cycle engines that people see can produce thrust but they don't need to in order for a jet engine to work, and in fact, air entering the combustion chamber is stagnated.
Okay, you are throwing around a lot of terms but I'm not sure that you understand what they are. For starters, the jet on your Jet ski is not the same as the jets used by airplanes. It is a gas motor otto cycle driven compressor pump that shoots water out through a nozzle as a "jet". The kinds...
I know the basic equations for airflow, but for some reason this question has been puzzling me: say you have a copper tube open at one end and connected to a piston cylinder system at the other. Air is drawn through the copper tube and into the cylinder as the piston moves from top to bottom...
Hello, I am working on a project this summer and I have run into a problem that I need a bit of help with. If I heat a fluid (water or some refrigerant) in a pipe with cross sectional area A and the fluid has a velocity V through the pipe then how long does the pipe need to be for a given heat...
Thank you very much for the help :). I do agree that my use of high and low pressure sides may have been a bit of an oversimplification. Sorry about that.
Hello everyone, I am a first year engineering student and I am really interested in learning about refrigeration (this isn't homework its my own personal interest). I have done a bunch of research but I am a little confused on a couple of points and was hoping that you guys could help me...
Hello, I am a first year engineering student and I have a short question about refrigeration systems. Just want to clarify that this is not a homework question. Yes I do think about things like this in my spare time its just personal interest. I'm taking engineering for a reason :tongue...
How would I go about calculating the motion of an object on a wave? For simplicity's sake let's just say its a sine wave. And this is an object on a water wave. Any pointers would be much appreciated. I'm interested in understanding how the mass of the object affect's it's motion in the vertical...
The thing works... if your saying that all of the force in a wave is vertical then that wouldn't change the function of my machine i.e. all of the motion in a compound wave is used to make the thing work so if the only motion is up and down then the thing still works fine. And i know the machine...
Thanks for the advice :). I actually developed the idea in my head and have a real working physical model of it. None of it was done with a computer... and its nothing like what you described lol. Honestly i really want to share it with you guys because i know once you see it your going to be...
