How many cubic feet in a 12 liter cylinder?

Answer 1

There is a fundamental difference in the system of measure of a cylinder in Europe and the USA.

Europe: Absolute interior volume in liters. You can think of this as how much water could be used to fill a tank (if this was used in the USA you could think of it as a X gallon tank)

USA: Gas in the tank at the tanks rated pressure. This is why when you convert 80cu FT to liters you get some bizarre number that doesn't seem accurate based on what we know of American Cylinder markings. (80 cuft = 2265 liters)

The most common question when it comes to tank size in the USA:

80 cuft at 3000 psi can be represented as:

80 cf/ 201.34 ATM = 0.397 cf (or cf/ATM)

0.397cf x 28.32 l/cf= 11.25 liters

12L tank at 3000 psi can be represented as:

12L / 28.32 = 0.4237

0.4237 * 201.34 = 85.31 cuft

12L is approximately an 85 at 3000psi. but... working pressure is 200 bar or 2900 psi... so the actual US equivalent is actually "smaller." above the 201.34 represents atmospheres... which is the metric unit "BAR"

so:

200bar * .4237 = 84.74 Cu FT

A standard European 12L Scuba tank is US equivalent 84.74 Cu FT

Or simply:

(X Liters / liters per cu ft aka 28.32) * atmopheres aka BAR = Us tank cuft markings

Here is a table borrowed from the ScubaBoard.com forums:

10 litre = 0.353 cf

2250psi tank... 54cf

3000psi tank... 72 cf

3300psi tank... 78 cf

3500psi tank... 83 cf

12 litre = 0.424 cf

2250psi tank... 64 cf

3000psi tank... 86 cf

3300psi tank... 94 cf

3500psi tank... 100cf

15 litre = 0.530 cf

2250psi tank... 80 cf

3000psi tank... 107 cf

3300psi tank... 18 cf

3500psi tank... 125 cf

20 litre = 0.706 cf

2250psi tank... 109 cf

3000psi tank... 143 cf

3300psi tank... 157 cf

3500psi tank... 167 cf

A simple explanation is 80cubic feet of air is 2265 litres at atmospheric pressure it is compressed to fit into a 12 litre tank by increasing the pressure to 3000 psi

Answer 2

Without an assumption, this question is unanswerable, so I assume that you are asking for the weight of 12 litres of water. 1 litre masses 1 kg, and 1 kg is 2.204 pounds.

12 * 2.204 = 26.448 pounds. ◄

If you need something other than water, take this answer and multiply by the specific density of the liquid in question. ■

Answer 3

1200 cubic feet = 33,980.22 liters.

Answer 4

1 foot = 12 inches

1 cubic foot = (12) 3 =1728 cubic inch
12 cubic inch = 12/1728 = 0.00694 cubic feet

Answer 5

A 10-inch diameter cylinder that is 12 feet long has a volume of: 11,300 cubic inches.

Answer 6

12000 liters is about 423.8 cubic feet.

Answer 7

10L = 0.353ft³

Answer 8

Depends on its dimensions.

Answer 9
