I work for a graphic equipment supply company that sells dry vacuum/pressure pumps and I have to create a chart at work, using Excel. On the (X) axis, it will be PSI (pounds per square inch/measurements 1.38 to 8.50) and on the (Y) axis, it will be CFM (cubic feet per minute/measurements from 0 to 500 with) . What formula do I use? For example, my PSI is 1.38...how do I figure out the CFM? Am I looking at the information the wrong way? Any help would be appreciated. I am really behind deadline

If I were to get a doctorate in Aerospace Engineering, would that be enough to become an astronaut? Now, I am not counting all the medical exams and stuff.

If not, what else would you need if you did not want to go into the test pilot, air force, and that type of stuff?

I was reading an article where a guy used water to cool the top of his house, it ran down the roof, then he had a pump recycle it and cool the house again with the same water. Occasionally he had to add more water but he said it worked fine. You think this would be an economical way to cool a concrete house with a concrete roof?

I want to do some science experiments, but I can't do it without some types of metal.

I want to know what the general cost of scrap copper, aluminum, and steel are per ounce. It would also help if you give me some safety tips when I handle the metal. Do I need a special type of soap to wash my hands after touching it? Should I wear rubber gloves and a mask?

Thank you for your time. Best answer will get ten points! Oh, and happy upcoming New Year everyone.
