Question: QUESTION #2: Double-Pine Heat Exchanger A single-pass co-current flow concentric-tube exchanger is required to cool 700 kg/h of oil from 350 K to 330 K.

QUESTION #2: Double-Pine Heat Exchanger A single-pass co-current flow concentric-tube exchanger is required to cool 700 kg/h of oil from 350 K to 330 K. Cooling water is available at 400 kg/h and 290 K. The inner stainless steel tube has a 30 mm inner diameter and the walls are 3.0 mm thick. The convective heat transfer coefficients of the hot oil in the shell and the water inside the pipe are 250 W/m2K and 150 W/m.K, respectively. The Cp of oil and water is 2.10 kJ/kg-K and 4.18 kJ/kg K, respectively. Determine the length of the heat exchanger in m
