big fan connected to small tube
Hi,
I have a question regarding fans and connecting them to a tube that is of a smaller diameter than the fan, a good example would be a vacuum, where you get big airflow through a very small tube. How much airflow is lost when you connect a bigger fan to a smaller tube ? For example 12x12cm fan connected to a 10x10 or 8x8 tube. I am guessing it depends on the power of the fan, for instance vacuum "fan" being 2000W and computer fan being 1 or 2W. Is there a formula to calculate how much is lost ? |
