Table 1 Mixing length and pressure drop for injection apparatus

From: An injection and mixing element for delivery and monitoring of inhaled nitric oxide

Description Mixing lengtha (cm) Pressure dropf (Pa)
Adapter A 47 ± 7b 2 ± 0
Adapter B 27 ± 1c 44 ± 3
Custom w/out constriction 23 ± 1d 33 ± 2
Custom w/constriction <7.8e 57 ± 5
  1. Values are mean ± standard deviation (n = 3)
  2. aThe worst case mixing distances of the three air flow rates and three target NO concentrations are shown
  3. bWorst case mixing occurred for 10 l/min and 10 ppm
  4. cWorst case mixing occurred for 10 l/min and 10 ppm
  5. dWorst case mixing occurred for 10 l/min and 20 ppm
  6. eIndicates that the NO concentration was within 5 % of the final target concentration by the first sampling point for all repeated experiments at each combination of air flow rate and target NO concentrion. The distance to the first sampling point is indicated
  7. fPressure drop was evaluated for air flow at 40 l/min
