Assignment: Direct Variation Investigation
In this investigation you are going to find the constant flow rate of different faucets around your house. You will use this rate to determine how quickly your faucets can fill up other containers.
Part 1:
Identify two faucets in your house to use for this investigation such as the kitchen sink, bathroom sink, bathtub, or garden hose.
Faucet 1 Description: ________________________
Faucet 2 Description: ________________________
Part 2:
Determine the time it takes each faucet to fill to a certain volume.
For each faucet:
- Turn on your faucet and allow the water to run.
- Once the water is flowing at a constant speed, place an empty 1-gallon milk jug under it.
- With a stop watch, time how long it takes for the gallon jug to fill up. This time is the number of seconds it takes for a gallon of water to flow from your faucet.
Number of seconds to fill a 1-gallon container from faucet 1 ___________
Number of seconds to fill a 1-gallon container from faucet 2 ___________
Part 3:
Write the unit rate of each faucet in gallons per second and in seconds per gallon.
Faucet 1 rate: r = _____________ seconds/gallon
Faucet 2 rate: r = _____________ seconds/gallon
Part 4:
Now use the rates and/or equations to fill in the table with how much time it will take your faucet to fill the following containers:
Container to be filled |
Time for Faucet 1 |
15-gallon kitchen sink |
|
32-gallon garbage can |
|
40-gallon bath tub |
|
2500-gallon swimming pool |
Container to be filled |
Time for Faucet 2 |
15-gallon kitchen sink |
|
32-gallon garbage can |
|
40-gallon bath tub |
|
2500-gallon swimming pool |
Part 5:
Write an equation for each faucet representing the relationship between x, the gallons to be filled in the container and y, the time it takes to fill the container.
Faucet 1: y = ____ x
Faucet 2: y = ____ x
