In an oil cooler, 216 kg/h of hot oil enters a thin metal pipe of diameter 25 mm. An equal mass of
cooling water flows through the annular space between the pipe and a larger concentric pipe; the oil and water moving in opposite directions. The oil enters at 420 K and is to be cooled to 320 K. If the water enters at 290 K, what length of pipe will be required? Take coefficients of 1.6 kW/m2 K on the oil side and 3.6 kW/m2 K on the water side and 2.0 kJ/kg K for the specific heat of the oil.
A. 1.45 m
B. 8.75 m
C. 2.67 m
D. 7.42 m
C. 2.67 m
