A closed tank of fixed volume is employed for the continuous mixing of two liquids, which enter at A, and B and are discharged completely mixed at C. The diameter of the inlet pipe at A is 150 mm and the liquid flows in at the rate of 56 dm3/s and has a specific gravity of 0.93. At B the inlet pipe is of 100 mm diameter, the flow rate is 30 dm3/s and the liquid with a specific gravity of 0.87. If the diameter of the outlet pipe at C is 175 mm, determine the mass flow rate, velocity and specific gravity of the mixture discharged.
