An airwater vapor mixture enters a steady-flow heater humidifier unit at state 1: 10C, 10% relative humidity,

Question:

An air–water vapor mixture enters a steady-flow heater humidifier unit at state 1: 10◦C, 10% relative humidity, at the rate of 1 m³/s. A second air–vapor stream enters the unit at state 2: 20◦C, 20% relative humidity, at the rate of 2m³/s. Liquid water enters at state 3: 10◦Cat the rate of 400 kg/h. A single air–vapor flow exits the unit at state 4: 40◦C, as shown in Fig. P11.142. Calculate the relative humidity of the exit flow and the rate of heat transfer to the unit.
