Question 1 Not yet answered A stream containing 5.7wt% chromium, Cr, is contained in the wastewater from a metal finishing plant. The wastewater stream is fed to a treatment unit that removes 96.2% of the chromium in its feed and recycles it to the finishing plant. The residual liquid stream leaving the treatment unit is sent to a waste lagoon. The treatment unit has a maximum capacity of 4900 kg wastewater per hour. If wastewater leaves the finishing plant at a rate higher than the capacity of the treatment unit, the excess (anything above 4900 kg/h) bypasses the unit and combines with the residual liquid leaving the unit, and the combined stream goes to the waste lagoon. Marked out of 5.00 Flag question 4 A wastewater from finishing TREATMENT @ Co recycled UNIT to finishing plant (no water) residual liquid stream plant to waste lagoon bypass Suppose that waste water leaves the finishing plant at a rate of 5950 kg/h. What is the mass flow rate of liquid to the waste lagoon? Dimensional quantity required (don't forget the unit) What is the mass fraction of Cr in this liquid? Decimal value required All your answers to three significant figures please
