Question

Some kids must of been playing pranks, last night. Someone got into my yard and turned the water hose on full. My yard and my neighbors is now flooded. How many gallons of water does a 5/8 inch water hose on full stream use over 12 hours ?
I need to know this to plan for the increase in my water bill. Thanks.

Answer 1

is that 5/8 inch inside diameter or outside diameter?
(you could time how long it takes to fill a 5 gallon bucket, then do some dividing)

Answer 2

/////////////////////////// she blinded me with science ////////////////////////////

I'm a scientist.

Well, not really. I'm just a state employee kicked around by a bunch of overpaid, underworked technocrats. Nonetheless, I do work in a science lab so ...

Let's experiment!!

Just ran over to the sink and filled a 1 liter graduated cylinder under the tap open all the way. The assumption made is the water pressure is approximately the same everywhere - 60 pounds is the standard, I think. The results of the experiment are as follows:

1.) I filled the cylinder in about 10 seconds

Now the question becomes "how much water is going to run out a standard garden hose in 12 hours?". Assumption number two is going to be the dimensions of the sink faucet and the hose are approximately equal. Therefore:

If the rate of water accumulation is 1 liter in 10 seconds, and if 60 seconds equals a minnute and 60 minnutes equals an hour, then the volume ought to be:

(1 liter / 10 seconds)*(60 sec/min)*(60 min/hr)*12 hr =4320 liters

Of course, there are about 4 liters in a gallon, so the approximate answer is 1000 gallons.

However, I'm racked with scientific doubt (as I ought to be). I made two assumptions, so I will back calculate to test my theory.

It just so happens there are 231 cubic inches in a gallon of water. This means the volume of water generated is 231,000 cubic inches. If the flood can be assumed to be an inch in depth, then the area of water is 231,000 square inches. There are 144 square inches per square foot, so this works out to be an area 1604 square feet , 1 inch deep. The linear dimensions are a patch of water 40 feet by 40 feet by 1 inch deep.

Are these roughly the dimensions of the flood? If not, you can do this experiment yourself. Just fill a 5 gallon bucket with the hose and calculate the volume the way I did. The major difference between my faucet and your hose is a ebulator which fills the stream with air bubbles. Assuming my water was 25% air by volume, this makes your actual volume 25% larger, about 1250 gallons.

Hope this helps.

Yawn. Another day's work. Time for a nap ......

Answer 3

depends on the pressure

go your water meter and read it - and write the number down
then check you past bills - see what you average per day usage is

then check the number of days into your cycle -
if 11 - subtract one and multiply by average use

if 30 gallons a day then 10 x 30 = 300
subtract from actual difference

call your water provider - may need to file a police report
to get the adjustment - because if you are connected to city
sewer =- then those gallons will really cost you

check NOW - so the law enforcement can see the damage -
do not wait until tomorrow when it has dried up

best of luck !

Answer 4

measure the volume coming out of the hose in a specified period of time, say 5 seconds. Then multiple your answer by 12*3600 seconds. We do not know the velocity of the water to be able to give you a closed form answer.
