A closed tank with fixed volume is used for continuous mixing of two liquid, which enter at A and B and discharged completely mixed at C$.$ The diameter of inlet pipe at A is $150$ mm and the liquid flows in at the rate of $56$ l$/$s and has a specific gravity of $0\mathrm{.}93.$ At B$,$ the inlet pipe is of $100$ mm diameter, the flow rate is $30$ l$/$s and the liquid has a specific gravity of $0\mathrm{.}87.$ If the diameter of the outlet pipe at C is $175$ mm$,$ what will be the mass flow rate and the specific gravity of the mixture discharged.
