Amixer combines two inlet streams to form a single outlet stream. one inlet stream adds 10 l/min of 5 wt% magnesium phosphate in water. the outlet stream must produce 35 l/min of a 2.2 wt% magnesium phosphate solution in water. assume the density of all solutions is identical and equals 1.200 g/liter. a [5 pts) sketch this system, label all variables. note if the information is a known or unknown variable (knowns have numeric values with units) b (5 pts write out a total mass balance around the mixer c.[5 pts) write out a water mass balance around the mixer d [5 pts) write out a magnesium phosphate mass balance around the mixer e [5 pts] calculate the mass fraction (or weight %) of magnesium phosphate in the second inlet stream f.[5 pts) how might your answer change if the density was not the same for each stream? 1 inch = 2.54 cm = 25.4 mm pw = 1000 kg/m3 1 kg = 2.205 lbm = 1000 g 1 atm = 760 mmhg = 101,325 pa 1 m3 = 264.2 gallons = 10001 density [] mass/volume mw [+] molecular weight, g/g-mol gravity = 9.81 m/s
