Figure 9.29 shows a system in which methyl alcohol at 77°F flows outside the three tubes while ethyl alcohol at 0°F flows inside the tubes. Compute the volume flow rate of each fluid required to produce a Reynolds number of 3.5 × 104 in all parts of the system. Then, compute the pressure difference for each fluid between two points 10.5 ft apart if the system is horizontal. All surfaces are copper.
