What type of cycle is an operation of a system with fixed capacity nozzles controlled by?

The operation of a system with fixed capacity nozzles is typically controlled by a low-high-low cycle. This type of cycle refers to a method of managing the flow and pressure within the system, allowing it to effectively adjust to varying demand levels while maintaining operational efficiency.

In a low-high-low cycle, the system operates at a lower pressure (or flow) initially, increases to a higher level when demand increases, and then returns to lower pressure as demand decreases. This cycle is particularly suited for systems where fluctuating demand is common, providing a balance between efficiency and responsiveness.

By working in this way, systems can prevent excessive energy consumption during low demand and ensure sufficient output during peak periods. The design of fixed capacity nozzles aligns well with this type of operation, as they can deliver consistent flow rates but require modulation in pressure levels to optimize performance depending on the operational conditions.
