The output for the 30% air-entrainment mask set at 8 L/min is 72 L/min,because 30% has nine total parts multiplied by 8 L/min,which equals 72 L/min.The total output for 40% should,therefore,be 72 L/min.There are four total parts in 40% multiplied by an unknown flow that equals 72 L/min.4X = 72.X is equal to 18 L/min.
