Question
Farmville derives its water from two sources, a deep well and a river. Water from the well has practically zero total dissolved solids (TDS), a conservative pollutant. The river is fed by two upstream tributaries with
the following properties:
Tributary A : Flow rate = 20 m3/s, 30 ppm TDS concentration
Tributary B : Flow rate = 30 m3/s, 25 mg/L TDS concentration
Flow rate downstream of the river is 46 m3/s.
A
→ 46 m³/s
B
Farmville
Well
Draw all necessary mass balance diagrams. Label properly.
b.
If the Farmville community needs 5.5 m/s to sustain its activities, how much water (in m³) does it extract from the well daily? Round off your answer to whole number.
What is the TDS concentration of the total delivered water to Farmville (mg/L)? Round off your answer to two (2) decimal places.
