Hi
I want to bury 100m of pic related under the ground, and push air through it.
Is there an easy way to calculate the airflow I will get through it?
I was thinking something like a computer case fan at each end (one sucking one blowing) which can be powered by batteries (this is going off-grid)
Would that be enough or would the air in the pipe be too heavy for such small fans to have any effect?
