4-61. Oil flows into the mixing tank through pipe A at 0.05 m3/s, and glycerin flows into the tank through pipe B at 0.015 m3/s. Determine the average density of the two fluids as the mixture flows out from the tank through the exit pipe at C. Assume uniform mixing of the fluids occurs within the 4m3 tank. Take po = 880 kg/m3 and pgly = 1260 kg/m3. mm
