That’s what the 4 stroke engine volume calculators do. www. Go figure. The calculations are assuming a speed of sound in the exhaust gas, which is not known exactly; also, it depends on the temperature and thus on fuel/air mixture and external conditions. Blowdown time-area is a better way to calculate blowdown and allows you to take the width of the ports into consideration.
