A double-pipe heat exchanger consists of two concentric tubes with one fluid flowing in the central tube

Question:

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 \(\left(15^{\circ} \mathrm{C}\right)\) water flows at 300 liters \(/ \mathrm{min}\) through a \(10 \mathrm{~cm}\) diameter inner tube and hot \(\left(50{ }^{\circ} \mathrm{C}\right.\) ) SAE 30 oil flows at 400 liters/min in the annulus between the inner tube and a \(12 \mathrm{~cm}\) diameter outer tube. The heat exchanger is \(2 \mathrm{~m}\) 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?
