MEDAL AND FAN PLEASE
Part A: Explain why we do not measure the rate at which water flows out through a showerhead 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 showerhead? Explain how the rate can be determined.

Cubic meters is a huge volume. That would not be practical to use for flow rate out of a shower head because the flow rate would be tiny, like .000001 cubic meters per second or something.

ohhhhhhh!!! Okay! I'm realllllyyyyy confused with part b for some reason?

joannablackwelder · Answer

Ok, it is one of those questions that is so simple it is hard! To find volumetric flow rate, you need to measure both volume and time. :)

joannablackwelder · Answer

Well, volume collected and time duration to be more specific.

piercetheveil47 · Answer

so i need to like do conversion or something?

joannablackwelder · Answer

No, you would need to collect a volume over a measured amount of time.

joannablackwelder · Answer

For example, 2 gallons collected over a minute time period.

piercetheveil47 · Answer

so can i write " you could measure the rate of water in gallons" ??

piercetheveil47 · Answer

((Thank you for helping me by the way This makes much more sense now!!)

joannablackwelder · Answer

No, you can measure the volume of water in gallons, and time yourself to figure out how long it took to collect that volume.

joannablackwelder · Answer

Then flow rate is volume/time period

joannablackwelder · Answer

And you are very welcome! :D

piercetheveil47 · Answer

so i don't understand what i can write? Like "You can measure the volume of water in gallons per minute" or something?

joannablackwelder · Answer

You could measure the volume of water collected for 1 minute exactly and that would be the flow rate in gallons per minute. But if you used any other time than 1 minute, you need to divide the volume by the time to find flow rate.

joannablackwelder · Answer

So, you could say something to the effect of collect a volume over a measured amount of time, then divide the volume by the amount of time used to collect the flow.
