Your course mate got bluff you or not?
Above is true only under certain scenario right?
suction pressure up can also = increase flow rate.
Example: You drink a cup of coke using a straw. The harder you suck, the faster/more coke goes into your mouth right? :think:
Don't flame me ... I am only a layman.
Yes.... i initially has the same thought... however... this only applies to blow rate, not suction rate.....
