how old is the wood, how dry or moist is it, how humid or dry is it where you are painting, how many coats are you applying for a good finish, are you sanding between coats, who is the manufacter of the paints, what type of wood is it-pine or maple. ALL THIS WEIGHS INTO YOUR QUESTION
how can you answer because so many things you dont know ie surface to be painted /thicck or thincoat/air temp/ ventulation / even out side temp will play somepart in the time span /how it is put on to the surface?spray /brush/pad /roller/
Depends on the paint, heat available and humidity.
