An open feedwater heater ( 2 inlets and 1 outlet configuration as shown below) operates at 5 bars with steady state flows (all states). Compressed liquid water at $$35^{?}\mathrm{C}$$ (state 1) enters at one section, while unknown status (either compressed liquid or mixture of water-vapor or superheated vapor) water enters at another section (state 2). The fluid mix and leave the heater as a saturated liquid (state 3). Ignore the kinetic and potential energy change and assume the open feedwater heater operates adiabatically. If the flow rate of compressed liquid is $$4,000\mathrm{kg}/\min$$ (state 1 ) and the mass flow rate of unknown status water is $$1,000\mathrm{kg}/\min$$ (state 2). $${\mathrm{T}}_0=298\mathrm{K}$$.
