The engine in Problem 3 has an exhaust pipe between the engine and catalytic converter that can be approximated as a round pipe, 1.5 m long and 6.5 cm inside diameter. Exhaust temperature leaving the engine is 477°C, and the average wall temperature of the exhaust pipe is 227°C. Calculate the exhaust temperature entering the catalytic converter. [°C]
