| What is the thickness of one quart of liquid (57.75 cubic inches) poured onto an area of 36x18 inches? |
Yeah, assuming that the borders of the area are going to contain the liquid, this is the number I got too, and I'm a kolidge ejikated enginear... |
A good way of checking your work is through cancelling units. 57.75 cubic inches (inch x Gives thickness of 0.08912 inches. And if the units don't cancel out, it means you did something wrong. Hope this helps. |

when I was in college one of the tests involved solving for lift distribution across a wing. There was a lot of matrix math (before personal computers, so we had to do matrices by hand). One girl in our class solved a 16x16 matrix BY HAND (sixteen simultaneous linear equations), and wrote a final answer with 12 decimal places. The instructor circled the last number in this long decimal string, and noted "error", and took a point off. We were all engineering students, and nobody was getting laid, so this is what passed for humor. |
Surface Tension of the liquid? |
