In a single heater regenerative cycle (as shown in fig.), the 1 kg of steam enters the turbine at 25 bar, 400°C and the exhaust pressure is 0.1 bar. The feed water heater of direct contact type operates at 5 bar.
The values of enthalpies at different states are shown in table:
If the entropy at states 1, 4 and 6 are 6.9212 KJ/kgK, O.6493 KJ/kgK and 1.867 KJ/kgK respectively, then the increase in mean temperature of heat addition (in∘C) after heat regeneration is
  • a)
    15.6
  • b)
    26.26
  • c)
    36.36
  • d)
    23.32
