A double-pipe heat exchanger consists of two concentrictubes with one fluid flowing in
Chapter 6, Problem 6.98(choose chapter or problem)
A double-pipe heat exchanger consists of two concentrictubes with one fluid flowing in the central tube and the other flowingin the annulus between the tubes. In a particular exchanger,cold (15 oC) water flows at 300 liters/min through a 10 cm diameterinner tube and hot (50 oC) SAE 30 oil flows at 400 liters/minin the annulus between the inner tube and a 12 cm diameter outertube. The heat exchanger is 2 m in length. (a) Calculate the pressuredrop in the oil stream (b) Can you calculate the pressure dropin the water using the same equations? Why or why not?
