Q4] (10 Marks) An exchanger to sub-cool condensate from a methanol condenser from 98 °C to 43 °C. Flow rate of methanol 110000kg/h. Water will be used as the coolant with temperature rise from 25 °C to 43 °C. The overall heat transfer coefficient is 600 W/m². °C. Calculate the heat exchanger area. Where water specific heat =4.18 kJ/kg.°C, methanol specific heat-2.84 kJ/kg.°C and F₁-0.85.
