SIMPLE TERRAIN INPUTS:

SOURCE TYPE = POINT

EMISSION RATE (G/S) = 10.0000

STACK HEIGHT (M) = 20.0000

STK INSIDE DIAM (M) = 0.5000

STK EXIT VELOCITY (M/S)= 30.0000

STK GAS EXIT TEMP (K) = 350.0000

AMBIENT AIR TEMP (K) = 315.0000

RECEPTOR HEIGHT (M) = 2.0000

URBAN/RURAL OPTION = RURAL

BUILDING HEIGHT (M) = 0.0000

MIN HORIZ BLDG DIM (M) = 0.0000

MAX HORIZ BLDG DIM (M) = 0.0000

THE REGULATORY (DEFAULT) MIXING HEIGHT OPTION WAS SELECTED.

THE REGULATORY (DEFAULT) ANEMOMETER HEIGHT OF 10.0 METERS WAS ENTERED.

BUOY. FLUX = 1.839 M**4/S**3; MOM. FLUX = 50.625 M**4/S**2.
