i have a point source with tracer mass loading of 0.17 kg/day. mass input units can be kg, grams or milligrams, as in the GMS unit’s menu.
if i use grams, the mass loading input should be 170 g/day, and respectively for mg.
the problem is with the output concentration units. i can chose between g/lit, mg/lit, ppm or ppb.
if i use concentration units of mg/lit, and change the mass units while updating the source value, i get different values for the solution.
it seems that the model is ignoring the input units, and take into consideration only the mass value itself.
for example - using 0.17 kg/day doesn't multiple with the correction factor for the output units, and i get very low concentration.
i would appreciate any advice.
