Fruit juice entering at 30 °C is being pasteurized in a double pipe counter flow heat exchanger using hot water entering at 97 °C and leaving at 65 °C. Specific heat of juice and water are 3.8 kJ.kg⁻¹.K⁻¹ and 4.2 kJ.kg⁻¹.K⁻¹, respectively. Flow rate of juice is 0.3 kg.s⁻¹ and that of water is 0.4 kg.s⁻¹. Considering an overall heat transfer coefficient of 1 kW.m⁻².K⁻¹, the area of heat exchanger required, in m², is _______. (Rounded off to 3 decimal places)
