A simple concentric tube heat exchanger is used to cool a roux sauce from 70 to 10°C. The inner tube has internal and external diameters of 50 and 55 mm, respectively, and the outer tube has an internal diameter of 110 mm. The water flows in the annulus at a velocity of 2 m/s and sauce flows in the inner tube at a rate of 2 kg/s. Determine the Reynolds number for each fluid. Data for roux sauce at 40°C: density = 1042 kg/m³, viscosity = 0.190 Pa s. Water density is 1000 kg/m³ and viscosity is 1cp.
