If the operation on a fluidised bed is a dense flowing fixed bed, then which one of the following method is used for pressure drop calculation?

If the operation on a fluidised bed is a dense flowing fixed bed, then which one of the following method is used for pressure drop calculation? Correct Answer Ergun Equation

Sieder Tate equation is used for flow without any particles, Kozeny Carman is for laminar flow regime in packed beds, and hence we use Ergun equation which is best suited as it was derived for turbulent packed beds.

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.
