> **Design Challenge statement**

Questions correspond to the steps in the Engineering Design Process.
 * **Ask** (What? Ask questions, understand the need, identify the problem, define)
 * **Imagine** (So what? Imagine, brainstorm, explore, discover)
 * **Plan** (Now what? Plan, design)
 * **Create** (Do it. Create, try it out)
 * **Improve** (If this then what? Improve, make it better)

Explore basic area and volume calculations, density of different liquids, safe operating pressures, types of materials used for handling different products.

 * Liquids and pipes - sample calculations**

You have two pieces of pipe. Pipe “A” is 12 inches in inside diameter (I.D.). Pipe “B” is 1 inch in inside diameter (I.D.). Both pipes are 100 feet long and filled with water. > a) What is the ratio of the cross-sectional areas of “A” and “B”. (calculate cross-sectional areas and ratio them) > b) What volume of water does each pipe hold. (multiply cross-sectional area by the length, adjusting for units) > c) What is the weight of the water in each pipe. (weight of water per unit volume times volume) > d) What would be the weight of gasoline in each pipe. (weight of gasoline per unit volume times volume) > e) Select a type of pipe and state the maximum safe operating pressure. (ASTM, CSA, or other source of pipe data) > f) You want to transfer water for use by people – what is this type of water called? (potable water) > g) Select a suitable type of pipe for transferring water per question (f) - above. > h) Bonus question – what is the total weight of the pipe and liquid in c and d > Show all calculations, all references for data used in the calculations, and links to these data.
