Engineering question

Local component losses, pipe friction and temperature-dependent properties had to be balanced consistently so parts remained comparable in the real system context.

Model & approach

Model line sections and connection components with common balance surfaces
Combine throughput and temperature states into traceable system characteristics

Boundary conditions

Liquid flow with temperature-dependent properties
Several line, coupling and operating variants

Results of the assessment

Fluid properties and local geometry losses shaped the resistance characteristic together.
Systematic balancing exposed which components governed each operating state.

Engineering consequence

The characteristics supported section sizing, component comparison and the pressure-loss budget of the complete circuit.
