Problem- What is the advective flux of total Cr that is discharged into a river (assume no Cr in the river before the discharge) with a flow rate of 15 m3/s from two leather tanning facilities? The first facility discharges 100 L/s of wastewater contaminated with 1 mg Cr/L, while the second one discharges at a rate of 50 L/s and a concentration of 15 mgCr/L. Consider the cross-sectional area of the river is 20 m2 after all discharges. Calculate the flux at point characterized by the cross-sectional area.
I need proficient help to explain each and every step in detail of the above problems.
