I want to determine the volume of air in a scuba tank. Can someone tell me the formula if I know how much water the tank holds?
Hopefully, your scuba tank doesn't contain waterbetz said:I want to determine the volume of air in a scuba tank. Can someone tell me the formula if I know how much water the tank holds?
It's probably worth pointing out that the ideal gas law is actually V = nRT/P, where n is the number of moles of gas present - probably the most important number, if you're interested in how much air is actually available to breathe.red_fox77 said:But better yet, to calculate the volume of air in the tank, use the ideal gas law (close enough for pure O2) V=RT/P. What this tells you is your pressure will depend on the temperature (in K) you are swimming at. R is the ideal gas constant, and the value depends on which units you want to use for V. Search google for 'R ideal gas' for some charts on which value to use.

[tex] V = \frac{2}{3}\pi r^3 + \pi r^2h [/tex]
The formula for calculating the volume of a cylinder is V = πr2h, where V represents the volume, π is Pi (approximately 3.14), r is the radius of the base, and h is the height of the cylinder.
The units of measurement for the volume of a cylinder are cubic units, such as cubic inches, cubic feet, or cubic meters.
To find the radius or height of a cylinder if the volume is known, you can rearrange the volume formula to solve for the missing variable. For example, if you know the volume and height, you can solve for the radius by dividing the volume by πh and then taking the square root of the result.
No, the volume of a cylinder cannot be negative. Volume is a measure of the amount of space an object takes up, and it is always a positive value.
The volume of a cylinder is the amount of space inside the cylinder, while the surface area is the total area of all the surfaces of the cylinder. The volume is measured in cubic units, while the surface area is measured in square units.
