The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x â¦4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
To calculate how much compressed oxygen you have, you need to know the capacity of your cylinder. Letâs call it 10 litres to make the sums easy. Next, you need to know the pressure in the cylinder. To make the sums easy, let's use kilopascals. Say the pressure is 10,000 kPa. One atmosphere is about 100 kPa. So your cylinder contains 100 atmospheres of pressure. If you vent the cylinder to atmosphere, it will release 10 litres x 100 atmospheres, i.e. 1000 litres of oxygen. This is all easy because oxygen is always a gas in the cylinder. Nitrous oxide is a liquid in the cylinder, which means the gauge pressure represents only the saturated vapour pressure of nitrous oxide, not the contents. If you want to know how much nitrous is in your cylinder, you need to weigh it. The tare weight (the
