7. An ideal mixing (total volume inlet = total volume outlet) of two incompressible fluids which is between water and methanol (SG=0.85) is coming from two inlets. At inlet 1 , water enter at 9m/s and at inlet 2 , methanol enters at 7m/s. The diameter of inlet 1 and 2 is 4cm and 3cm. If the outlet diameter is same as inlet 2 , calculate the mixing velocity and density of the mixture at the outlet
