Bowl size and smoke time.

[jaytex1969]

So, I'm trying to get a feel for pipe/bowl size and the time commitment to properly enjoy a smoke.
My little Baraccini pocket size #135 has a bowl depth of 0.9" and inner diameter of 0.6".
I've already determined that this pipe smokes great with a not quite so densely packed load and small sips.
Filled to the brim, it's a nice 20 minute affair.
My not yet used Stanwell #185 has a depth of 1.7" and inner diameter of 0.7. Someone commented in another thread that this would be a 90 minute adventure.
I know technique and tobacco variables will apply.
Anyone found any loose rule of thumb to predict burn time?
Please share your related observations.
Thanks.

There are too many variables to really predict burn time; blend components, tobacco cut, bowl size, chamber shape, environment, cadence, draft hole, packing technique, etc...
General rule of thumb for me; Small bowl (Group 2's and smaller) = short duration (30 min. and less), medium bowl (Group 3's and 4's) = longer duration (30min. to an hour), large bowl (Some Group 4's, Group 5's, and above) = longest duration (an hour +).

My not yet used Stanwell #185 has a depth of 1.7" and inner diameter of 0.7. Someone commented in another thread that this would be a 90 minute adventure.

The specs you list would last me 45 minutes to an hour. All my pipes have chambers either at or somewhere close to 1.5" deep and .74" wide. I'm never smoking for an hour and a half. My pipes are what they are because I like to smoke for about an hour, or a little less, at a time.

As mother points out, the variables are many on top of volume of tobacco you can properly load a chamber with.
If you use the same tobacco, same moisture, packing, cadence, etc., etc., it should bear a linear relationship with the volume.

Thanks, fellas.

When I first started out I could (and often did) finish an average sized bowl in a mere twenty minutes. Then I learned how to smoke properly and those same pipes would easily give me an hours smoke.
Worth considering ::

Bowl sizes are not uniform even if you have the same circumference at the rim and depth, because of the shape of the chamber. The Dunhill Groups 1 to 6 and beyond are a generalized concept and not a technical specification. The blend and cut throw the whole game into the unknown. Flake, plug, coin and rope cuts burn more slowly, some much more slowly, so you can get "a full length" smoke (whatever that is) out of a small pipe, like Group 1 or 2. The moisture in the blend is also a key. So, this is part of the art of pipe smoking, and is inspired guesswork accompanied by length of experience. It is something you learn with specific pipes, blends and cuts.
