A second stream of water, at inlet 2, enters the heat exchanger through second circular pipe with a temperature of 40°C and a pressure of 700 kPa. The inlet 2 pipe has a cross sectional area of 25 cm 2 . The two streams are thoroughly mixed and leave the heat exchanger at exit 3 through a circular pipe with a volumetric flow rate of 0.06 m 3 /s, a pressure of 700 kPa, and as a saturated liquid. Find: (a) The volumetric flow rate at inlet 1, in m 3 /s, (b) The mass rate of flow at the exit 3, in kg/s, (c) The mass rate of flow at inlet 2, in kg/s and (d) The velocity in the pipe at inlet 2, in m/s....
