Oil introduced into a coil immersed in a stirred vessel is used to provide heat that is being absorbed by an endothermic reaction occurring inside the vessel. The heat absorbed from the contents in the vessel per hour is 7320 kj. The inlet and outlet temperatures of the oil are 150°C and 100°C, respectively, while the temperature of the contents in the vessel is measured as 80°C after attaining steady state conditions. If the overall heat transfer coefficient of the system is 250 W/m² K, what is the effective heat transfer area? O 0.2 m² O 8.1 m² 0.7 m² O 733 m² O 32.4 m²
