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 9 m/s and at inlet 2, methanol enters at 7 m/s. The diameter of inlet 1 and
2 is 4 cm and 3 cm. If the outlet diameter is same as inlet 2, calculate the mixing velocity
and density of the mixture at the outlet.
