A power plant burns 10^4 kg h^-1 of coal containing 2.5% sulfur. The effluent is released from a single stack of height 70m. The plume rise is normally about 30 m, so that the effective height of emission is 100m. The wind on the day of interest, which is a sunny summer day, is blowing at 4 m s^-1. There is no inversion layer. Use the Pasquill-Gifford dispersion parameters.

Question

A power plant burns 10^4 kg h^-1 of coal containing 2.5% sulfur. The effluent is released from a single stack of height 70m. The plume rise is normally about 30 m, so that the effective height of emission is 100m. The wind on the day of interest, which is a sunny summer day, is blowing at 4 m s^-1. There is no inversion layer. Use the Pasquill-Gifford dispersion parameters. 

 

  1. Plot the ground-level SO2 concentration at the plume centerline over distances from 100m to 10km. (Use log-log coordinates.)
  2. Plot the ground-level SO2 concentration versus crosswind distance at down-wind distances of 200m and 1 km. 
  3. Plot the vertical centerline SO2 concentration profile from ground level to 500 m at distances of 200m, 1km, and 5 km.
