Class PressureCondition

java.lang.Object
neqsim.process.logic.condition.PressureCondition
All Implemented Interfaces:
LogicCondition
public class PressureCondition extends Object implements LogicCondition
Condition that checks if pressure meets a specified criteria.

Supports comparison operators: >, >=, <, <=, ==, !=

Example usage: 

// Check if pressure is above 5 bara
PressureCondition minPressure = new PressureCondition(stream, 5.0, ">");

// Check if pressure is stable at 10 bara (within tolerance)
PressureCondition stable = new PressureCondition(stream, 10.0, "==", 0.5);
