Upstream of the turbine, the air has velocity v u, and the flow has an area A u, at the disk is has v t, A t, and downstream v d, A d. The pressure of the air on the upstream side of the disk is P1 and on the downstream side is P2. The ambient pressure is P0. The pressure difference either side of the actuator disk is how the power is extracted.

Methods for sampling and analysing air emissions. NSW industries and commercial premises can ensure they comply with NSW air quality regulations by sampling and analysing their emissions of air pollutants. Approved methods for the sampling and analysis of air pollutants (AMSAAP) (PDF 160KB) lists the methods that must be used to sample and analyse.

Furthermore, as is evidenced by the dangers of miners on the front lines of coal collection, coal is not a clean energy source. Burning coal releases hazardous emissions such as carbon dioxide, mercury, sulfur, and other toxic chemicals into the air. The consequences are widespread health issues and damage to the global environment causing and worsening climate change.

Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants. Baghouses came into widespread use in the late 1970s after the invention of high-temperature fabrics (for use in the filter media) capable of withstanding temperatures over 350 °F (177 °C).
