% Example 3.2 Rating a multistream shell-and-tube heat exchanger
% This example is taken from Luo et al. (2002). A three-stream
% shell-and-tube heat exchanger is used to heat two cold streams with one
% hot stream. The exchanger structure is shown in Fig. 3.17. The design
% parameters are presented in Table 3.1. Calculate the outlet temperatures
% of the fluid streams.
