A steam power plant operates on a theoretical reheat cycle as shown below. Steam enters high pressure turbine at 150 bar and 550°C (h3 = 3450 kJ/kg) and expands upto 40 bar (h=3050 kJ/kg). It is reheated at constant pressure to 550°C (h5 = 3560 kJ/kg) and expands through the low pressure turbine to a condenser at 0.1 bar (h= 2300 kJ/kg). Also given, h (at 0.1 bar) = 191.8 kJ/kg. Thermal efficiency (in %) and steam rate (kg/kWh) of the plant neglecting pump work are, respectively
