1. Compressed air

Hello, I am interested in finding out the electric power output from a compressed air system. i see that there is a formula for calc. it with the amount of compressed air required to generate about 1 W with a pressure of 1 bar is given by Compressed air(cu.mm/s) = (1000 N-mm/s) / (0.1...
2. Image visibility

i have this projector setup with a light source having about 500 lumens as its light output.I know the distance to the fresnel lens which will be at the focal distance so that parallel light goes through the lens. I want to know how much of this light would be falling on the fresnel lens. I...
3. Information on photoluminescence?

Can anyone tell me any good websites which have information on photoluminescence? Also, i have an lcd projector with a light source which has about 500 lumens as the light intensity.If i need to project an image of an chess board on the lcd onto the screen with the best contrast say for a 32...
