Web1. With viscous gas flow through a leak, the leakage rate is proportional to the difference in the squares of the pressures acting across the leak. The VF is calculated at 21°C (70°F) per Equation 2. 2. With viscous liquid flow through a leak, the leakage rate is proportional to the pressure difference. The VF is WebTypically, one runs the Inlet Leak Check to confirm whether there's a leak (the leak rate you determine is only approximate), the symptom of which is usually low pressure and/or smaller, longer retention time peaks; if there is a leak confirmed, one would follow this test up with the Pressure Decay test, which is more stringent and precise. recipes with elderflower cordial
