If you are asking about a 27' circumference pool, then the answer is 27'
27 bags of 30kg bags of concrete bargs
27 1 cu ft bags or 9 3 cu ft bags.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level.
A cubic yard is 3x3x3= 27 cubic feet so you would need 27/.5 = 54 bags
a 27 foot round by 52 inch deep pool holds 18,550 gallons of water
20 lbs takes us 0.2 cubic feet; a yard is 27 cubic feet; that would take 27/.2 = 135 bags. That is a lot of bags, with total weight of 2700 pounds
A 27-foot wide by 52-inch-deep round pool holds a maximum of about 18,551.7 gallons of water.
18 - 19 uprights is the average.
depends on how deep it is
The answer depends on what the 27' refers to: the radius, diameter or circumference of the pool. A pool which is 27' across will cover 572.6 square feet.
1 yard = 27 cu ft; 2 yard = 54 cu ft at 2 cu ft per bag, that is 54/2 = 27 bags
