Design procedure of harmful substances concentration in the ground layer atmospheric air at their emissions by the single source

Abstract

The variant of a design procedure of concentration of harmful substances in a ground layer is offered at emissions by a single source of the enterprise on the basis of ОНД-86. For simplification of algorithm of calculations and programming some groups of the equations are replaced by approximation by one equation. As a result the quantity of the equations and conditional commands is reduced approximately to 50% 'if' in the program. Numerical comparison with the calculation example, resulted in ОНД-86, has shown that an error of the offered variant of calculation no more than 5% that quite arranges practice of calculations. It is established that the maximum of ground concentration decreases with increase in difference of temperatures between temperature of emissions and atmospheres. Other calculations are resulted.
