Jet sizes .... ?

[victor3]

A while ago I experimented with the difference in jet sizes between 0.4mm and 0.7mm. To my surprise I found that it took more or less exactly 7 minutes to shift 2 litres of water, regardless of the jet size! :?

I would have thought that the 0.7mm would have shifted the volume in about one third of the time of the 0.4mm one, but apparently not.

So, is the purpose of the jets just to reduce or increase the size of the droplets? :roll:
