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.

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

Transcribed Image Text:2. 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.
