Question

Part A: Explain why we do not measure the rate at which water flows out through a shower head in cubic meters per second? In your explanation, use reasoning based on appropriate units to model this situation. (5 points)

Part B: What are the two quantities that should be measured to find the rate at which water flows out of a shower head? Explain how the rate can be determined. (5 points)

Answer 1

Do you have a rough idea of how big a cubic meter is? That should inform your answer.

Answer 2

"cubic meters" monster1551, not linear meters.

Answer 3

Cubic meters is an appropriate unit for water volume, but it's a bit extreme for a normal household shower.

Answer 4

cubic meters? No @CliffSedge

Answer 5

do not have any idea.

Answer 6

Well, the point is, a cubic meter is like a large bathtub full of water. Imagine an entire bathtub full of water hitting you every second. It's too large of a unit to be easy to express without scientific notation.

Cubic centimeters would be a lot better, or maybe even liters. 1 liter = 1000 cc's (and a cubic meter is 1000 liters, to give you a sense of scale).

All you would need is a liquid measuring cup and a stopwatch to figure out the flow rate.

Answer 7

Oh, my gosh, thanks so much. You really know how to explain things.

Answer 8

I already completed the test, though. :(

Answer 9

Eh, at least you got some insight into how to reason through problems. Use your imagination and intuition to guide you.

Answer 10

Thanks.

Answer 11

what is the awnser

Answer 12

Ahem, I uh didn't write anythin' in the essay question, but @CliffSedge gives a decent explanation in his last comment @seabass035
