A mixing chamber operates steadily at 200 kPa with 2 kg/s of saturated liquid H2O mixing with 1 kg/s of superheated steam at 250°C. Determine the exit specific enthalpy and exit temperature if the heat transfer rate into the mixing chamber is 150 kW throughout this process.
Note: I know how to solve for the exit specific enthalpy, but I am not sure how to solve for the exit Tempurature. Could you please show me how to solve for the exit Temperature. Thank you.

2.(40 pts.) A mixing chamber is used to heat liquid water to a saturated vapor by adding superheated steam. The liquid water enters through Line 1 at 1 MPa, a temperature of 100 C and a mass flow rate of 2 kg/s. The superheated steam enters through Line 2 at 1 MPa and 400°C. The combined stream exits through Line 3 as a saturated vapor at 1 MPa. The chamber also receives 3 MW of heat transferred from an external...
Liquid water at 20ºC, 100 kPa enters one inlet of an open-feedwater heater (a mixing chamber) with a flowrate of 0.5 kg/s. Superheated vapor at 200ºC is added at the other inlet. Determine the mass flowrate (in kg/s) of water vapor that must be added to produce a liquid-vapor mixture with a quality of 75% at the exit.
