Sorry for not explaining clearly.
There are many heat exchangers on the pipeline,
and the pressure loss of the heat exchanger is currently known.
Assuming the pressure loss of the heat exchanger is 0.5bar,
how can I simulate the pressure loss of the heat exchanger
to find the actual pipeline pressure.
In the simulation, because the pressure loss of the heat exchanger
was not set, the pump flow rate was too large and the curve deviated
from the BEP point.
Please refer to the attachment file.
By the way, I tried to use AUTOMATIC VALVE to set the pressure loss,
but it didn't seem feasible.
Your assistance greatly appreciated,
