[Public-list] Mufflers

[Roger L Kingsland]

Bill,

One thing I recall when investigating my exhaust system is one manufacturer 
recommended that the capacity of the water lift (muffler) be large enough to 
hold the amount of water that drains back (down) from the exhaust hose 
leaving the water lift.  I guess that's better than having it back up into 
the exhaust manifold.

They suggested assuming the hose is half full of water; so, if you have a 2 
inch hose, half the volume per linear inch is about 5 cubic inches (1 inch 
radius x 3.14159 squared / 2).  If the part of the hose that drains back to 
the water lift is 6 feet, the water lift should have a minimum capacity of 
355 cubic inches or, at 0.004329 gallons per cubic inch; drum roll please, 
1.54 gallons.  Please note, I am not an engineer (but I played one in my 
high school play 36 years ago) so you will need to confirm for yourself if 
any of this stuff makes sense.

Roger
