Cold water cp 418 kJkgK enters a heat exchanger at 15°C at a rate of 05 kgs where it is heated by hot air

Cold water (cp = 4.18 kJ/kg.K) enters a heat exchanger at 15°C at a rate of 0.5 kg/s, where it is heated by hot air (cp = 1.0 kJ/kg.K) that enters the heat exchanger at 50°C at a rate of 1.8 kg/s. The maximum possible heat transfer rate in this heat exchanger is (a) 51.l kW (b) 63.0 kW (c) 66.8 kW (d) 73.2 kW (e) 80.0 kW
