because it has clorine
Reflection and refraction. You see the reflection on the bottom of the surface of the pool. You see the refraction of light through the surface of the pool. This is the super short answer...someone else might provide more information but the reader can "google" reflection and refraction to find out more.
At the very bottom of the pool are the bottom drains . By regulation , they must be 36" apart . Either of these drains must be able to support the total suction of the filtration system . Theis is the Virginia Grahme Baker regulation . At other places on the pool bottom you may see smaller discs . These are the returns , the outflow of the filtration system .
At the bottom of the pool.
Put a scratch and sniff sticker at the bottom of a pooll lol. the best joke in the world. don't you think... Put a mirror at the bottom of the pool. (Got it from breaking dawn.) :) It's funny because I'm blonde. (Y)
Try casting a flocculant let it settle for a couple of days and then vacuum the bottom layer of water to waste you will see the layer you want to remove on the bottom of the pool. check with your pool shop for a good brand of flocculant.
So that they can see out far into the ocean. And in a pool- so that the glare of sunlight or lighting is reduced on the surface which enables lifeguards to see to he bottom of the pool. The standard height is 2 metres of the ground.
There is no filter at the bottom of a pool. Perhaps you are looking at the hydrostatic valve which is there in case your pool is emptied and Will make sure that the pool wont float in ground water.
What is the foreshadowing of Percy sitting at the bottom of the pool for 7 minutes?
If there is a film laying on the bottom of the pool it is most likely that the pool has clarifier or floculant put in it. If so let the pool settle for a day or two until all of the clarifier and contaminant has settled to the bottom then turn the filter to waste and gently vacuum the cloudy material on the bottom of the pool to waste do not put floculant through the filtration vac it to waste.
Bottom of the pool is circular in shape and its radius is 9 feet. Thus area of bottom of pool = pi x r2 = 3.14159265 x 92 = 254.469005 sq. feet
Note that the question is asking about the area of the bottom of the pool.. which by the question we can see is a cylinder shaped pool.. The bottom of the pool is a circle so, area of circle = (pie)r2 (where are is the radius) 1 diameter = 2 x radius 8 feet diameter = 4 feet of radius so the answer will be = 3.142 x 4 x 4 ( 4 is multiplied to time because the formula is r2 [note the square on the r] ) = 50.272 (Answer ) Approximate area of the bottom of the pool is = 50 square feet.
