Abstract

In many places data for σy have been measured. By combining these data, we found that σy for non-buoyant plumes from tall stacks can be given by
$${\sigma _y} = 0.079\,\, \times {\,^{0 \cdot 86}}{\sigma _{\rm A}}^{0 \cdot 57}$$
independent of roughness, stability and source height. For a rising buoyant plume
$${\sigma _z} = 0.6\Delta h$$
has been found. Using this, the maximum ground concentration for a rising plume is found when the plume rise is 2 x stack height at a distance x = (0.6 hS u QH 0·33)1·5, so that this distance depends on the wind velocity. A formula for the maximum concentration is given.
