Which of the following best describes the efficiency of dry scrubbers at removing particles that are less than 2 micrometers in
diameter? Dry scrubbers are less than 20% efficient at removing particles less than 1μm and increase to over 50% efficiency at removing particles between 1 and 2μm. A Dry scrubbers are between 50% and 90% efficient at removing particles less than 2μm, depending on the flow rate. B Dry scrubbers are between 5% and 40% efficient at removing particles less than 2μm in size. C Dry scrubbers are less than 10% efficient at removing particles less than 1μm in size.
Answer: dry scrubbers are less than 10% efficient at removing particles less than 1μm in size
Explanation:
A dry scrubber or dry scrubber system is one type of scrubber that is used to remove harmful materials from industrial exhaust gases before they are released into the environment. That substance then falls out of the gas stream or is caught in a particle screen.
The closest distance between the orbits of these two planets is about 24 million miles. But the actual distance between the two is constantly changing because they orbit the sun at different speeds. At the farthest, these two planets are 162 million miles apart.
