Solve the below problem:
Q: Liquid acetylene, C2H2, is stored in a high-pressure storage tank at ambient temperature, 25°C. The liquid is fed to an insulated combustor/steam boiler at the steady rate of 1 kg/s, along with 140% theoretical oxygen, O2, which enters at 500 K. The combustion products exit the unit at 500 kPa, 350 K. Liquid water enters the boiler at 10?C, at the rate of 15 kg/s, and superheated steam exits at 200 kPa.
a. Calculate the absolute entropy, per kmol, of liquid acetylene at the storage tank state.
b. Determine the phase(s) of the combustion products exiting the combustor boiler unit, and the amount of each, if more than one.
c. Determine the temperature of the steam at the boiler exit.
