Figure 9.32 shows a heat exchanger with internal fins. Compute the Reynolds number for the flow of brine (20% NaCl) at 0°C at a volume flow rate of 225 L/min inside the heat exchanger. The brine has a specific gravity of 1.10. Then, compute the energy loss over a length of 1.80 m. Assume that the surface roughness is similar to that of commercial steel pipe.
