This segment was copied, pasted, and rotated 60-degrees multiple times, and placed on all the corners of the hexagon. I draw a line segment from the top node of my hexagon down. I had this feature turned on for the majority of my node-manipulation work. On the right hand side, there is a toolbar, with a button to allow "snap to cusp nodes".This will change the object to a path, which will let us manipulate it more easily. Select the hexagon and press "Shift+Ctrl+C". It may help to go into the Document Properties and turn off grid-snapping for this. Use the same technique as that used for the circle in the previous step, but stop when the corners of the hexagon contact the edge of the circle. Drag the cursor to a corner, where it will snap to the grid to form your perfect, 1" diameter circle. Click the center of the grid, and hold down "Shift" and "Ctrl". Set default unit to "inches" "width" and "height" to 1 and grid to 1/16" or. To draw the center turbine, I did the following in Inkscape: IT helped me find my way around and will help you follow the instructions below better. Not familiar with Inkscape? I highly recommend reading through this first. Everything was kind of made up as I went along since I'd never used the program, and had no purpose in mind for the final product. I designed my compressed air turbine in Inkscape. gif showing the air molecules being compressed, and then moving the turbine! I hope it helps! The gases will move toward the center of the turbine, where they exit the exhaust hole. As it moves through it, the air will push the fins, and cause the turbine to rotate. The compressed gas will move through the turbine to the area outside the turbine. The concept that a high pressure gas will move to an area of lower pressure is the concept that will drive our compressed air turbine. If you have a container filled with a gas that has had extra atoms pumped into it, and you open the container, the high pressure atoms will move to the area with the low pressure atoms until the overall pressure is equal. By using a pump, one can force more gas atoms into a space, increasing the pressure. The pressure of a gas is a reflection of how many atoms are forced into a given space. Gases can be held at different pressures. So freely in fact, that gases don't have a "form", and instead take the form of whatever container they are in. In a gas however, the atoms are able to move around freely. The atoms are forced together and don't flow around much. In solids, these atoms are packed very tightly together, which is why they are -erm, solid.
Let's start from the very beginning, shall we? All matter is composed of atoms.
