A concentric tube heat exchanger of length L=2m is used to thermally process a pharmaceutical product flowing at a mean velocity of um. c=0.1 m/s with an inlet temperature of Tc, i=20oC. The inner tube of diameter Di= 10 mm is thin walled, and the exterior tube (Do=20 mm) is well insulated. Water flows in the annular region between the tubes at a mean velocity of um, h=0.2 m/s with an inlet temperature of Th, i=60oC. Properties of the pharmaceutical product are υ=10 X10-6 m2/s, k=0.25 W/mK, rho=1100 kg/m3, and cp=2460 J/kgK. Evaluate water properties at Th= 50oC.
