For some conceptual aspects regarding pipeline pressure drop calculations, please refer to the diagram

Problem description: Fluid is diverted from point A to points B and C. Therefore, I am interested in the pressure loss in the DN200 tee connecting to point B (other pressure losses are not the focus of my question), as well as the pressure loss in the DN200 branch pipe leading from A to C； Pressure loss of DN200 three-way DC from point F to point E ； Pressure loss of the DN200 tee branch from point D to point E ； Is this analysis correct?
It shouldn’t be analyzed in that way, although I don’t quite understand it
It should be calculated using Bernoulli’s equation: Pressure head at A = Pressure head at E + Pressure drop across AE. The pressure drop across AE equals the pressure drop along path ACDÉ, which in turn equals the pressure drop along path ABFE. I think (not necessarily true) that there is no pressure drop from A to B, while there is a loss of dynamic pressure head from A to C.
