A cocurrent double-pipe exchanger (see Figure E3.2) exists to cool the process stream described previously (q₁
= 100 L/min = 1.67 × 10⁻³
m³/s) from 80 to 50 ◦C. The process fluid flows in the inner pipe, and the chilled water flows in the outer pipe (Figure 3.10), T_2F
= 5 ◦C. Determine the flow rate and exchanger exit temperature of the chilled water that will be needed.

The following table shows the pipe characteristics for the exchange
