An industrial wastewater is discharged into a river about 0.5 km downstream from an outfall (discharge) coming from a desalination plant. Upstream of the desalination plant's outfall the river has a flow of 17.8 m3/sec and a total dissolved solids (TDS) concentration of 260 ppm. The water coming from the desalination plant's outfall flows into the river at a rate of 1800 L/sec and has a TDS concentration of 4,450 ppm. The industrial wastewater discharge has a flow of 5.0 m3/sec and a TDS concentration of 860 ppm
a) Calculate the flow in the river just downstream of the desalination plant's outfall (m3/sec).
b) Calculate the flow in the river just downstream of the industrial wastewater discharge (m3/sec). c) Calculate the TDS in the river just downstream of the desalination plant's discharge (ppm). d) Calculate the TDS in the river just downstream of the industrial wastewater discharge (ppm).
