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.

Hot oil is pumped through a heat exchanger (see figure below) at a flow rate of 0.5 L/s. An inlet manifold equally distributes the oil into 20 parallel, 5-mm-diameter copper tubes that are about 1 m in length. The oil cools down as it flows through the copper tubes. Oil then exits through an outlet manifold. The viscosity of the oil is 250 centipoise and its density is 950 kg/(m^3). Assuming uniform pressure in the manifolds and laminar flow through the tubes, calculate the total head loss (in meters) across those 20 copper tubes.

Water flows in the annulus of a hori- zontal, concentric-pipe heat exchanger and is being heated from 40°C to 50°C in the exchanger which has a length of 30 m of equivalent straight pipe. The flow rate of the water is 2.90 x 10 3m/s. The inner pipe is 1-in. schedule 40 and the outer is 2-in. schedule 40. What is the pressure drop? Use an average temper- ature of 45°C for bulk physical properties. Assume that the wall temperature is an average of 4°C higher than the average bulk temperature so that a correction can be made for the effect of heat transfer on the friction factor. ompnongibia Flow Starting with
