Hot oil at 110°C heats water from 30°C to 70°C in a counter-current double pipe heat exchanger. The flow rates of water and oil are 50 \(kg min^{-1}\)and 100 \(kg min^{-1}\) respectively, and the specific heat capacities are 42\(kJ kg^{-1} °C^{-1}\) and 20 \(kJ kg^{-1} °C^{-1}\) respectively. Assume the heat exchanger is a steady state. If the overall heat transfer coefficient is 200\(Wm^{-2} °C^{-1}\), the heat transfer area \(m^2\) is
