How many galons of water in a 21 foot pool?

The area of a cilinder is Pi r 2 x h (where h is the height of the pool. the result is given in f3 , and Pi is= 3.1416.. so you have: r= 21/2= 10.5 f then 3.1416 x (10.5)2x 5 f the the Volume of the pool given for example 5 f tall is=1731.8 f3

convertin to galons =

12 954.763 Galons

How many liters of water are in a 16 foot round pool that is 4 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

so in your case, 16*16*4*5.9=6000 gallons=23000 liters

How many gallons are in a pool 6 ft X 4 ft 2 in X 1 ft 5 in?

Assuming you mean 6 foot diameter round pool, 2 feet deep. V=pir2h=3:14159*(3)2*2=56.5 cu ft. 56,5 cu ft x 7.48 gal/cu ft = 423 gallons

How many gallons of water in a pool 35X90 that is 3 ft deep?

Answer1000 gallons is way off. The formula for acquiring the number of gallons a pool contains is the following: 1) Multiply the length x width (in this case 35w x 90length = 3150 square foot. 2) Figure out the average depth by adding the deep end and the shallow end together (ex. what is the depth in the shallowest end and what is the depth in the deepest end). If it is a rectangle pool it's easy to figure (in this case you gave the depth at 3 ft., I will assume that is 3 ft. all the way around) 3) After adding the deep end with the shallow end divide by two. This gives you the "average" depth of the pool as a whole (once again, in this case the only number you've given is 3. If the whole pool is 3 ft. deep then the average depth is 3 ft. deep) 4) Now, multiply the square footage with the average depth (in this case, 3150 x 3 = 9450. 5) You then multiply that number by the constant of 7.5 (in this case 9450 x 7.5 give you 70,875 gallons of water)

Your answer to how many gallons of water are in a 35 x 90 foot pool is 70,875.

Answeralmost 1,000 gal

How many gallons are in a 30 ft round pool 56 inches deep?

You would use the following formula: 30 (dia.ft) X 30 (dia.ft.) X 4.66 (avg.depth.ft.) X 5.9 (multiplication factor) = 24,744.6 gallons of water

Diameter is 15 feet and height is 4 feet what is the total volume in gallons of water in the swimming pool?

The volume of a cylinder is V= pi* (D/2)^2* H Where: pi=3.14... D=diameter H=height In this case: V= 3.14*(15/2)^2 *4 = V = 3.14*(7.5)^2*4 V = 3.14*7.5*7.5*4 V= 706 cubic feet (approximate since pi was rounded to 2 decimal places) Number of gallons in 706 cu ft really depends on the temperature of the water. For water roughly at 34 degrees Fahrenheit 1 cu ft of water = 7.480519 gallons So gallons of water in pool = 706* 7.480519 = 5281.25 gallons. Since this is a swimming pool that is probably used at temperatures well above 34 degrees. The number of gallons will be less than the 5281.25. The actual number of gallons will be saved for the next math/physics/chemistry lesson.

Who is responsible for pulling permits, the homeowner or the swimming pool contractor?

The swimming pool contractor generally performs this function. However, the law holds the homeowner responsible for making sure it is done.

I recently had a swimming pool built. What type of fence should I put up to prevent my dogs from getting in there when I am not around?

Is Chlorinated water good for bathing in?

Depends on the level of chlorination.

in fact almost all fresh water which is delivered by a municipal system has some level of chlorine in it. This is to kill off any bacteria that may be in the water; this is not a very high level though.

Swimming pool water is also normally chlorinated for the same reason, although the levels of chlorine are higher and can irritate the eyes and mouth if too strong.
