pitmath — Draft & Stack

An openly provisional physics calculator for sizing barbecue-pit stacks, throats, and reverse-flow gaps under real conditions such as altitude, wind, fuel moisture, and target cook temperature.

Why it surfaced

This is unusually specific software with unusually honest caveats: it says its heat-loss coefficients are uncalibrated, its fuel-burn estimate runs roughly 40–50% high, and its recommendations are provisional. Its altitude model distinguishes airflow from oxygen mass, then turns the result into a concrete retrofit—8-inch NPS pipe and a widened throat for the sample pit at 7,300 feet.
