    The heat exchanger considered has two baffles within
    the shell and with the tubes arranged if five passes.
    The case is similar to 796 of PHOENICS library one but
    the same resistance to flow exerted by tubes is introduced
    by PLANT settings.
            ============================
    User-defined variables
    T1IN = inlet temperature of shell fluid
    T2IN = inlet temperature of tube fluid
    FLO1 = mass-flow rate of shell fluid
    FLO2 = mass-flow rate of tube fluid
    COEF1 = heat-transfer coefficient on shell-fluid side
    COEF2 = heat-transfer coefficient on tube-fluid side
    COEF12 = overall heat-transfer coefficient from fluid 1
           to fluid 2
    RESCO = flow-resistance coefficient of the tube bank
  ENDDIS
  PLANTBEGIN
    Resistance to flow exerted by tubes, throughout the shell.
