[TheForge] Power hammer Vs air hammer (OT)

[Demon Buddha]

That's a pretty good nit, I must confess.  I suppose we could pick nits 
even more by making some arbitrary constraint about relative volumes of 
fluid to solid, and then pick nits about the arbitry value.  Then, of 
course, we could work our way down the nit ladder until we were arguing 
about quarks and spin and charm and strangeness... finally getting down 
to strings and super strings and how doing that tends to make one's mind 
seize up.

But seriously, that is a good point.  However, the motion of the fluid 
in a solid-link hammer (SL) is usally not constrained the way it is in a 
fluid link hammer (FL).  That is, in SL hammers the fluid is allowed to 
escape in whatever volumes it may choose.  That it doesn't go completely 
dry immediately is due to surface phemomena rather than containment. 
Whereas, in an FL hammer, the efficiency of operation is very strictly 
dependent upon the degree of containment.  With much leakiness, the 
power of an FL cannot be transmitted from source to destination without 
much loss.  I may be wrong, but I think this constitutes a fundamental 
difference between the two in terms of the roles of fluids in each type 
with respect to power transmission from source to work.
