I presume you mean at a depth of 180 feet. Since the weight of a cubic foot of water is approximately 65 pounds, the weight of water on a square foot at that depth is 65 times 180, which is 11,700 pounds. That is the pressure per square foot. Since there are 12 x 12 or 144 square inches in a square foot, the pressure in pounds per square inch would be 11,700 divided by 144, or about 81. This is in addition to the barometric pressure, which is about 14 pounds per square inch, for a total of 95 psi.
Answer 1
It's not possible for a water tank to be 180 feet. One of its dimensions could be, however.
Sadly, since we don't know which dimension it is, nor do we know the height of
the tank or the depth of the water in it, nor do we know at what level or in which
direction you want the pressure measured, there's no way at all to even begin to
work on a solution to this question.
48 square feet will give you more than enough and reduce backwashing frequency.
Length times width in feet will give the square footage.
Multiply the two dimensions to get the area. The calculation will give you 24 square feet.
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 7*17 = 119 square feet.
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 12*15 = 180 square feet.
An acre has 43,560 square feet. The multiplication give you 1,742,499 square feet.
To calculate water pressure in pounds per square inch (psi), you can use the formula: pressure force / area. This means that you divide the force exerted by the water on a surface by the area of that surface. The result will give you the water pressure in psi.
The length times width will give you the area. So this comes out to 60 square feet.
There are 144 square inches in a square foot. The calculation will give you 9.5 square feet.
You just have to multiply the two lengths to get the area. This will give you 31.9464 square feet, or just 32 square feet.
Measure its side in terms of feet. Multiply that measure by itself to give the area in square feet.
There are 9 square feet in a square yard. The calculation would give you 3.33 square yards.
One acre has 43,560 square feet. Multiply that be 16 will give you a total of 696,960 square feet.
Multiply the two dimensions to get the area. The calculation will give you 525 square feet.
Assuming that the room is 12 FEET by 28 FEET the area is 336 square feet.
There are 9 square feet in 1 square yard. The calculation will give you 18 square feet.
Multiply the two dimensions to get the area. The calculation will give you 189 square feet, which converts to 21 square yards.
