###### OXYGEN E1

###### INDIVIDUAL OXYGEN SUPPORT

approximate mathematical calculations per capita consumption: -

An average adult at rest inhales and exhales about 8 liters of air per minute: therefore in a day about 11 thousand liters of gas are breathed in total. The inhaled air is made up of about 2% of oxygen, while the exhaled air contains only 15%, therefore about a quarter of the oxygen is "consumed" with each breath: it is carried through the arterial blood from the lungs to the cells. of the body, which in return give carbon dioxide to the venous blood. Each human being therefore consumes an average of 550 liters (about 0.5 m3) of oxygen per day.

###### CALCULATED AVERAGE CONSUMPTION OF 100 GREENHOUSE CITY OF 100 INHABITANTS

every citizen of the greehouse city needs 550 liters of oxygen per day, therefore for a small community of inhabitants of 100 people approximately 55,000 liters of oxygen are needed.

___________________________________________________________________

There are about 100 communities of greenhouse cities in the world for a total of about 10,000 inhabitants between men, women and children for a total consumption of oxygen (only oxygen that corresponds to a quarter of that inhaled 25%) for a total of oxygen consumed: -

about 55,000.00 (55 million liters) exhaled per day of oxygen for 1 community

about 220,000,000 (millions of liters) inhaled per day of oxygen for 100 community
