A double-pipe heat exchanger consists of two concentric tubes with one fluid flowing in the central tube and the other flowing in the annulus between the tubes. In a particular exchanger, cold (15 C) water flows at 300 liters/ min through a 10 cm diameter inner tube and hot (50 C) SAE 30 oil flows at 400 liters/ min in the annulus between the inner tube and a 12 cm diameter outer tube. The heat exchanger is 2 m in length. (a) Calculate the pressure drop in the oil stream (b) Can you calculate the pressure drop in the water using the same equations? Why or why not? a) 8.79 kPa B) No
