Water (1.25 kg/s) is to be heated from a pipeline temperature of 15°C to 85°C using superheated steam (13.75 kg/s) at 550°C and 3 MPa in a steady-state process to produce 15 kg/s of heated water. The heating is to be done in a mixing tank by directly injecting the steam, all of which condenses. Calculate the entropy generated (Sgen) for this process (in kJ/kg*s). Assume no heat loss
