Stability Parameter For stable situations, the stability parameter, s, is calculated: s=g[(dT/dz)/T_{a}] (16) As a default approximation, for stability class E (or 5) dT/dz is taken as 0.020 K/m, and for class F (or 6), dT/dz is taken as 0.035 K/m. Stable  Crossover Between Momentum and Buoyancy For cases with stack gas temperature greater than or equal to ambient temperature, it must be determined whether the plume rise is dominated by momentum or buoyancy. The (DT)_{c} is determined and solving for DT, as follows: (DT)_{c}=0.019582 T_{s} v_{s} s^{1/2} (17) If the difference between DT exceeds or equals (DT)_{c}, plume rise is assumed to be buoyancy dominated, otherwise plume rise is assumed to be momentum dominated. Stable  Buoyancy Rise For situations where DT exceeds (DT)_{c} as determined above, buoyancy is assumed to dominate. The distance x_{f} is determined by x_{f}=2.0715 u_{s} s^{1/2} (18) The plume height, h_{e}, is determined by h_{e}=h_{s}+2.6 [F_{b}/(u_{s}s)]^{1/3} (19) Stable  Momentum Rise Where the stack gas temperature is less than or equal to the ambient air temperature, the assumption is made that the plume rise is dominated by momentum. Then, h_{e}=h_{s}+1.5[F_{m}/(u_{s}s^{1/2})]^{1/3} (20) The equation for unstableneutral momentum rise is also evaluated. The lower result of these two equations is used as the resulting plume height.
