A cascade impactor measures the flow rate range and particle size of a substance dispensed through an aerosol. It collects samples in a graduated manner through a series of discs, with each disc representing a stage of the impactor. The impactor has ten stages, with each stage collecting smaller particles than the previous one. The […]
The Cascade Mountains are a 725-mile mountain range with 92% in the US. It has an east-west range of 194 miles and is known for its rugged terrain, snow-capped peaks, and active volcanoes. Mount Rainier is the highest peak and has a national park. The Cascades have 18 active volcanoes, and the Columbia River divides […]
Cascade control is a process control strategy that uses two control loops to control a process variable. The primary loop provides the secondary loop with a setpoint, and the secondary loop controls disturbances before they affect the primary control objective. The secondary loop should have faster process dynamics than the primary loop, and flow controllers […]
