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.
