aim of research to find if rain decrease co2 level in air, and what is minimum time to make the level of co2 constant in closed place with water shower and air fan. I need this calculation to buy right air fun.
Hello Damira
CO2 concentration reduction in air can be measured by subtracting the carbonic acid in the water before the artificial rain from the collected water after the rain. It significantly depends on air and the droplets temperature and air humidity, all of which increase solubility and decrease air CO2 concentration.
You can refer to this paper for more info.

Selecting the suitable fan depends on various factors including the dimension of the room. This needs a little knowledge about the eddy flows so that you can manage the air. You can refer to this paper to know indoor eddy flows better.
