For the binary cycle shown, the enthalpies are h1 = 3,166 kJ/kg; h2 = 2,290 kJ/kg; h3 = 178 kJ/kg; h4 = 184 kJ/kg; ha = 354 kJ/kg; hb = 273 kJ/kg; hc = 112 kJ/kg; and hd = 113 kJ/kg. The mass flow rate in the topping cycle is 3.9 kg/s. What is the heat transfer in the condenser? Express your answer in kW.
