 02 Mar 2013 04:23 AM I have a 25 liter vessel with a 1" outlet and two 1/32" outlets. The gas formed upon combustion has a density of approximately 2.9 g/Liter at a temperature of 383 K and 3.2 Atmospheres pressure. If the pressure occurs spontaniously via internal combustion inside the vessel, how much of the gas goes out through the 1" outlet and how much through the 1/32" outlets in grams per second as the pressure falls from 3.2 Atmospheres to Atmosphereic pressure? Cp/Cv = gamma = 1.32 the viscosity of the gas at 1.013 bar and 0 °C is 0.00008 Poise; the Compressibility Factor (Z) at 1.013 bar and 15 °C is 0.9775. The Thermal conductivity at 1.013 bar and 0 °C is 13.99 mW/(m.K).
