It is desired to heat 230 kg/h of water [cp = 4.175 kJ/kg.°C] from 35 to 93 °C with oil [cp = 2.1 kJ/kg.ºC] having an initial temperature of 175 °C. The mass flow of oil is also 230 kg/h. Two counter-current flow double-pipe heat exchangers are available: Exchanger 1: U = 570 W/m².°C, A = 0.47 m² Exchanger 2: U = 370 W/m².ºC, A = 0.94 m? Analyze the suitability of the heat exchanger in completing the above task.
