Crush strength of a particle is an indication of the particle’s attrition properties which are necessary to study attrition and erosion of the fluidized bed.

Crush strength of a particle is an indication of the particle’s attrition properties which are necessary to study attrition and erosion of the fluidized bed. Correct Answer False

Crush strength is not indicative of the attrition property of particles. It is rather static and used for packed bed applications and not fluidized bed applications. Attrition is caused by dynamic forces, therefore can be tested by ball mill testing, jet mill testing, etc. A study of attrition gives us data on the erosion of the bed as well.

Bed bugs are parasitic insects in the genus Cimex that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known as it prefers to feed on human blood. The name bed bug derives from the preferred habitat of Cimex lectularius: warm houses and especially near or inside beds or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed. A number of adverse health effects may results from bed bug bites, including skin rashes, psychological effects, and allergic symptoms. Bed bugs are not known to transmit any pathogens as disease vectors. Certain signs and symptoms suggest the presence of bed bugs; finding the adult insects confirms the diagnosis. Assuming the information in the given paragraph is true, choose the correct statement.
