Class UtilityStreamSpecification

java.lang.Object
neqsim.process.equipment.heatexchanger.UtilityStreamSpecification
All Implemented Interfaces:
Serializable
public class UtilityStreamSpecification extends Object implements Serializable
Specification object describing the utility side of a single-stream heater or cooler.

This class stores the supply and return temperatures together with optional minimum approach, heat-capacity rate and assumed overall heat-transfer coefficient so the mechanical design package can derive an approximate size when only the process stream has been simulated.
