Aussie Phil,

Although your advice is good, unless you are a Physicist, Process or Instrumentation Engineer please don't bother as Coriolis and it's techniques would be way too much information for this guy who doesn't even realise what Hemisphere he is inhabiting.

I seriously don't mean any disrespect here but i am an Instrument Engineer and unless we stop this thread quickly we'll soon be comparing realtive torque vs pressures vs latitude vs flow vs vessel shape etc ....etc......

Whadd'ya reckon we all just leave him be to watch his sink draining in whichever direction he fancies?......although personally I prefer to think that either he's been drinking too much...or not enough.....or whose to say that he wasn't exactly sure what kind of mushrooms were in his soup last night?.........either way , as long as it actually drains who cares anyway?
