In a regenerative cycle steam with enthalpy of 3514 kJ/kg is expanded in h.p. turbine to state
corresponding to saturated enthalpy of water equal to 613 kJ/kg. If the pump work requirements
in high pressure and low pressure zones are respectively 3 and 1 kJ/kg., amount of heat
transferred in boiler is
(a) 2897 kJ/kg (b) 2898 kJ/kg (c) 2904 kJ/kg (d) 2905 kJ/kg
