1.4 A steam turbine is operating at a steam flow rate of 550 kg/s with an enthalpy of live steam h, of 3670 kJ/kg and enthalpy of exhaust steam h, of 2010 kJ/kg. The condensate enthalpy h, at the condenser outlet is 140 kJ/kg. Calculate (i) the power output of the steam turbine, (ii) the rate of heat rejection in the condenser, and (iii) the required cooling water flow in the condenser, where its temperature increases by AT-w= 11 K. The specific heat of water is 4.19 kJ/kgK.

1.4 A steam turbine is operating at a steam flow rate of 550 kg/s with an
enthalpy of live steam h, of 3670 kJ/kg and enthalpy of exhaust steam
h, of 2010 kJ/kg. The condensate enthalpy h, at the condenser outlet is
140 kJ/kg. Calculate (i) the power output of the steam turbine, (ii) the rate
of heat rejection in the condenser, and (iii) the required cooling water flow
in the condenser, where its temperature increases by ATw = 11 K. The
specific heat of water is 4.19 kJ/kgK.
