is a 5 inch rvk right

[nicc1976 155]

I was hoping that some one on here can tell me if a 5inch rvk fan in a ds120 tent is good to take the hot air out and replace it have tried to work it out but not sure any help thanks

depends how many m3 per hours it can get out of the tent. it has to empty the room every 5 minute or so more or less to be good for heat.
