The above 3 formulas are used for solving problems involving flow rate calculations.
If you know 2 of the 3 variables the third can be calculated.
As usual, here at www.1728.com, we have a calculator that will do all the work for you.
This ultra calculator is special by allowing you to choose among a
great variety of units. Unlike other calculators, you are NOT
confined to inputting volume in liters, time in minutes, etc. making this calculator
quite versatile. Let's see some examples.
1)
Using a garden hose that has a rate of .75 gallons per minute, it took you 2.5 hours to fill
up a swimming pool. What is the volume of the pool?
The most important step in using this calculator is
FIRST CHOOSE WHAT YOU ARE SOLVING FOR.
In this case we are solving for VOLUME so click on that button.
Enter 2.5 in the "time" box and choose hours from its menu.
Enter .75 in the "rate" box and choose gallons per minute from its menu.
Click the CALCULATE button and you will see this equals 15.039 cubic feet
PLUS you get to see the answer in 7 other different units !!
2) A 9 cubic yard cement truck is pouring cement at a rate of 80
cubic feet per minute. How long does it take to pour out all the cement?
FIRST CHOOSE WHAT YOU ARE SOLVING FOR.
In this case we are solving for TIME so click on that button.
Enter 9 in the "volume" box and choose cubic yards from the menu.
Enter 80 in the "rate" box and choose cubic feet per minute from the menu.
Click the CALCULATE button and your answer will be 182.25 seconds OR 3.0375
minutes OR 0.050625 hours.
3)
A faucet can fill a 1 gallon jug in 90 seconds. What is the flow rate?
FIRST CHOOSE WHAT YOU ARE SOLVING FOR.
In this case we are solving for RATE so click on that button.
Enter 1 in the "volume" box and choose gallons from the menu.
Enter 1.5 in the "time" box and choose minutes from its menu.
Click the CALCULATE button and your answer is 42.06 cubic centimeters per
second PLUS answers in 23 other units.
Here's hoping this calculator helps you with those math problems.
For easy readability, the answers are displayed in a "significant figure" format so you will
not see answers such as 77.3333333333333333.
Numbers larger
than 1,000 will be displayed in scientific notation and with the same number of
significant figures specified. You may change the significant figures displayed by
changing the number in the box above.
Internet Explorer and most other browsers, will display the answers properly but
there are a few browsers that will show no output whatsoever. If so, enter a zero
in the box above. This eliminates all formatting but it is better than seeing no
output at all.
