A boiler produces dry saturated steam (i.e., quality = 100%) at 3.5 MPa by exchanging heat between a furnace gas and saturated liquid water. The furnace gas enters this heat exchanger at a temperature of $T_{inlet} = 1100$ + the last three digits of your Z-ID. The furnace gas leaves the heat exchanger at a temperature of 430°C. The furnace gas has an average specific heat of $c_p = 1.046$ kJ/kg-K over this temperature range. If a saturated liquid water enters the boiler heat exchanger at a mass flow rate of 12.6 kg/s, determine:
a. the heat transferred from the furnace gas to the saturated liquid water,
b. the exergy loss by the furnace gas,
c. the exergy gained by the steam,
d. the entropy produced during this process.
Neglect heat losses from the boiler to the environment.
