Gnielinski pipe equations
Extends from Greenhouses.Flows.FluidFlow.HeatTransfer.BaseClasses.PartialSinglePhaseCorrelation (Base class for single-phase heat transfer correlations), Greenhouses.Flows.FluidFlow.HeatTransfer.BaseClasses.PartialPipeCorrelation (Base class for heat transfer correlations for pipe flow).
Information
The model Gnielinski extends the partial model PartialSinglePhaseCorrelation and computes the heat transfer coefficient based on the Gnielinski correlation.
