Hello all.
I modelled a BHE geothermal heat pump system and studied the impact of temperature on a contaminant. In my contaminant transport simulation, I put concentration of 100 mg/L in some nodes around a bhe and ran a heat and mass transport simulation (with biodegradation included) for 1 year. I wanted to know the initial mass correlated with initial 100 mg/L and final mass of contaminant after 1 year to see how much contaminant is degraded. I wonder how I could get total mass from concentration?
