I appear...

On the K100 I eventually purged the system and went to the top dot grade
fluid (Castrol I think). I also fitted stainless bleed nipples at the
callipers which had one way valves (ordered from US) which made bleeding
a cinch. It *still* had to be repeated every month or so to keep it in
top fettle. Thinking about Champs comments about the disks, early K's
did not have floating disks so I eventually made floating calliper
mounts (!!)(1) which helped considerably. The 9R has floating disks tho.

Cos it's the only thing you haven't changed

Seriously, I can't explain that. I didn't realise they were coming up
good, then going away over a couple of days. The only logical
explanation for that is that there's a leak of somesort somewhere.

 

Badly wrong, too.

Why would too small bubbles compress less than one large one of the
same total volume?

 

Champ proposed

I think it should be correct though. The ratio between the combined
surfaces of two bubbles and one bubble with a equal total volume is
about 1.25, which means that the smaller bubbles experience less
pressure per surface unit at the same displaced volume.

 

Uh oh, here we go again.

Where? Don't think this is one of the often repeated ukrm threads, is
it? Did I miss a meeting?

 

Simian proposed

So product of pressure and volume equals n(?) times the molar gas
constant and absolut temperature, I'm not quite following you here. The
pressure should always be the same irrespective of bubble size,
depending on depth (outside pressure) and temperature. That doesn't
take surface tension into account though. Wonder what effect that would
have and at what scale.

 

It does actually say in the book to use extra heavy duty stuff, so I'll get
what they recommend when changing the other bits and bobs.

 

Simian proposed

yup, so the errors of my ways.

Oh, didn't even notice what this was originally about. Just got
interested in the part if smaller bubbles exhibit different
characteristics to larger ones.
