WebThe duration of the cylinder can be calculated with this formula: volume (in liters) × pressure (in bars) / 40 - 10 in minutes (the 10 is subtracted to provide a safety margin), so a 6-liter cylinder, of 300 bar, is 6 × 300 / 40 - … WebNov 9, 2024 · Calculation Formula. WC (kg/ltr) X Pressure (bar) = TV. TV / 40 (lpm) = TD. Less Safety Factor = TD – (WC (ltr) x Whistle (Bar) / 40 lpm) = WD. Operators of SCBA should be able to calculate this on the run using the pressure guage to establish a running calculation of the expected duration. Example: an operator is on a SCBA mission, is using ...
