question

If the exhaust gases contain 0.22% of NO by weight, calculate (i) The minimum value of \delta allowable if a NO reduction rate of0.032 lb/ft^2hr is to be achieved. (ii) The corresponding minimum allowable value of K. Use the following data. The gases are at: T = 1200°F P = 18.2psia Average molecular wt. of the gases = 30.0 Effective rate constant K = 760 ft/hr Diffusion coefficientD_(_1)m = 4.0 ft^2/hr

  1. \delta = 0.0028 ft, K = 55 lb/ft^2hr
  2. \delta = 0.0040 ft, K = 45 lb/ft^2hr
  3. \delta = 0.0050 ft, K = 60 lb/ft^2hr
  4. \delta = 0.0032 ft, K = 47 lb/ft^2hr
  5. \delta = 0.0045 ft, K = 44 lb/ft^2hr
  6. \delta = 0.0024 ft, K = 49 lb/ft^2hr
  7. \delta = 0.0032 ft, K = 50 lb/ft^2hr
  8. \delta = 0.0018 ft, K = 42 lb/ft^2hr
  9. \delta = 0.0026 ft, K = 47 lb/ft^2hr
  10. \delta = 0.0035 ft, K = 52 lb/ft^2hr
