public class SimpleTPoutPipeline
extends Pipeline

Simple pipeline model with specified outlet temperature and pressure.

This class provides a simple pipeline model where outlet conditions are directly specified rather than calculated from flow correlations. Useful for preliminary calculations or when detailed pressure drop modeling is not required.

Example Usage

SimpleTPoutPipeline pipe = new SimpleTPoutPipeline("simple_pipe", inletStream);
pipe.setOutTemperature(300.0); // 300 K
pipe.setOutPressure(50.0); // 50 bara
pipe.run();
