Is there an equation with which I can estimate the flow rate a fan will generate at a set diameter, speed and angle of the blades? Assume that this is a simple box fan that you would put in your window. I'm assuming that you would have to determine the axial speed of the air given the angle...

I am a fresh BSME graduate with an overall GPA of 2.8/4.0. After filtering through a bunch of job sites online, I must say that I am getting a little discouraged because I see requirements of 3.0+. It is unfortunate because after getting my act together my final two semesters were ~3.3. I...

Ok so the phase change is generating high pressures. Through heating a gas a pressure increase can be achieved but, you suggest that it isn't nearly as dramatic as a phase change. This brings up something else that I have had on my mind in the past; is there a way to calculate the pressure...

Generally the working fluids in a power generating system is either water (steam) or air. This I imagine is because they are widely available fluids. The specific heats of these ranging from some 1 - 2 kJ/kg-K. For the sake of argument, let's assume that hydrogen or xenon are equally...

I know force times velocity is power. I would assume that this is what you need to use. EDIT: oops didn't realize how old this thread was.

You would lose power due mostly to the engine having to overcome friction in both the engine itself and in the generator.

If you are talking about air flowing only through a straight smooth (no friction) pipe then it would go a little something like this. We can assume that 800psi is well above choked pressure as russ_waters has said. This means your air can only go as fast as the speed of sound. speed of...

Ah OK, that makes sense. Thank you!

My setup as requested goes a little something like this: Pressurized Air tank ===> Nozzle ===> Turbine ===>Atmosphere I am doing this in a "lab" type setting so, all conditions are controllable. You are correct in that the kinetic energy is coming from my potential "dam" of compressed...

I should have specified that this is in fact an impulse turbine. Where energy is extracted by way of changing the kinetic energy of the fluid. It is not a Pelton wheel but, a Boundary Layer Turbine (aka Tesla Turbine). They are relatively simple in design and construction. The principle is still...

Hi all, I am working on designing a simple turbine for my senior design project. What I am trying to figure out is what the available power in a fluid stream is. I am thinking of the kinetic energy equation but instead of a given mass, I have mass flow rate, which gives units of Watts. Power...
