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. 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.

Answer 2

im not good with word problems

Answer 3

hold on

Answer 4

is that all of it

Answer 5

yeah

Answer 6

If we did measure in cubic meters per second, the value would be quite small, like 0.003
So using cfs has the rate become a whole number, like 3cfs
Make sense?

Answer 7

no

Answer 8

Pretend that the show head rate is 3 cfs

When that rate is converted to cubic meters it becomes 0.085 cubic meters. See how it becomes a decimal number? Usually when showing quantities like rate, it's appropriate to show them as whole numbers, not decimal numbers.

And if 3 cfs were converted to gallons per second it would be 22.4 gallons per second.

All three of these are the same rate, just different units.

Answer 9

Because in the US and Canada, we measure in cubic feet per second. The rest of the world does it in cubic meters per second. It's the difference between US customary units and SI units.

Answer 10

im still confused on this

Answer 11

i dont know what to do for Part B
