Mathematics of Breathing in the ISS RS.
The Electron-VM oxygen production system in the Russian section of the International Space Station can operate in several modes with different current consumption. For example, with a current of 16 amperes it is able to process 1.6 liters of water per day, 32 amperes - 3.2 liters.
One cosmonaut needs a volume of oxygen to breathe on the station during the day, which Electron-VM produces from about 1 liter of water. Therefore, a team of three people needs about 3 liters of water per day.
What if the system breaks down?
In space, the principle of duality always applies. We previously told you that two Electron-VM systems are installed in the Russian section of the ISS - in the Zvezda and Nauka modules. And in case they are off, there is a supply of compressed oxygen delivered to the station in tanks from Progress cargo ships, as well as solid fuel oxygen generators ("oxygen bombs").
