if they are under water about 30 seconds after their lungs run out of oxygen.
Technically, none. A square foot is a measure of area whereas it is the volume of water that is required. To convert from area to volume it is necessary to know the depth. A twelfth of a cubic foot will cover an area of one square foot to a depth of 1 inch. A cubic foot will cover it to a depth of 1 foot, 100 cubic feet will cover it to a depth of 100 feet.
None. A lineal foot has length but no width (or depth or height).
30536.28 gallons By figuring your pool's depth, you can then determine how much water your pool holds. This is how you would find the average depth: shallow end depth + deep end depth divided by 2. Rectangular pool: Lenght x Width x average depth x 7.5 total gallons. Oval pool: full width x full length x average depths x 5.9 total gallons. Sloping sides: If your pool has sloping sides, multiply the final figure by .85. Hope this helps. === === An 18 foot round by 42``tall pool holds 7300 to 7500 gal.
about 2 psi. (0.5 psi / foot of depth)
920 sq yards with 40-foot frontage
15 foot round? About 5000 gallons, if it's four feet deep. Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5
Not if you let your foot off of its head.
i have a pool that has a 10 by 30 foot width/length and a 4 to 11 ft shallow to deep end depth ; how man gallons, an estimate is this? the pool is a standard square?
no they would drown
I think you would also need the distance where the slope up to the shallow end starts.

If you're face first in it then yes you can drown in it.
1 foot
Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 16*16*4*5.9=6000 gallons=23000 liters

You're mixing metric with imperial units??? Here's a formula for round pools: distance across*distance across*depth*5.9 for rectangles: length*width*depth*7.5 or for a deep end: length*width*((shallow end depth + deep end depth)/2)*7.5 so in your case, 16*16*4*5.9=6000 gallons=23000 liters
