40 pressure balancing loop diagram
The piping common to both the secondary and primary loop s are the two tees and the common piping shown above. Rule "1" tells us to keep that common pressure drop very low. The reason being if there is nothing to stop it, the pressure drop in that pipe will cause a flow in the secondary circuit, even if the secondary pump is off. course of action included in the diagram . For example, an increase in “Production Pressure ” may increase “Production Output,” but it may also increase “Stress” and decrease “Quality” 5. All balancing loop s are goal-seeking processes. Try to make explicit the goals driving the loop . In causal loop diagram s, balancing loop s are noted by a “B,” a “—,” or a scale icon in the center of a loop . The Structure of Balancing Loop s. There is always an inherent goal in a balancing process, whether it is visible or not. The basic structure of a balancing loop involves a gap between the goal (or desired level) and the actual ...
