Mass Balance Derivations
Qup: Stream flow rate upstream from masstransfer process
Qin: Inflow volume or flow rateQmix: Resulting volume or flow rate from mass
transfer process (Qup + Qin)Tup: Stream temperature directly upstream
from mass transfer processTin: Temperature of inflowTmix: Resulting stream temperature from mass
transfer process assuming complete mix
All water temperatures (i.e. Tup, Tin andTmix) are apparent in the FLIR sampledstream temperature data. Provided thatone instream flow rate is known, the otherflow rates can be calculated.
