where 0 ; is the variance of the lateral spread and T&u) = T(x, 0). i.c., the
temperature difference from the center line of the plume. Figures 2 and 3
show. respectively, the relationships between T and y and between T and y2
for some x's. Then To and 0,' can be estimated. taking Eq. ( 1 ) into account.
These are tabulated in Table 111.
