What are the differences between laminar flow and turbulent flow?
What are the differences between laminar flow and turbulent flow?
Laminar flows are smooth and streamlined, whereas turbulent flows are irregular and chaotic. A low Reynolds number indicates laminar flow while a high Reynolds number indicates turbulent flow. The flow behavior drastically changes if it is laminar vs. turbulent.
Where are biofilms found?
Sites for biofilm formation include all kinds of surfaces: natural materials above and below ground, metals, plastics, medical implant materials—even plant and body tissue. Wherever you find a combination of moisture, nutrients and a surface, you are likely to find biofilm.
What are the differences between laminar flow and turbulent flow quizlet?
– A laminar flow moves in nearly straight-line paths parallel to the stream channel; a turbulent flow moves in an erratic fashion with horizontal and vertical swirling motions.
Why is it important to understand the difference between laminar and turbulent flow?
The motion of a fluid’s particles between the layers of the substance is what determines if the flow is laminar or turbulent. The distinction between laminar and turbulent flow is extremely important in engineering because the type of flow impacts how mass and heat are transferred.
What is the difference between biofilm and planktonic bacteria?
Whereas planktonic bacteria is designed to colonize new niches, but with a lower chance of survival, bacteria in a biofilm provides a more secure way for bacteria to reproduce and survive. This explains, in part, biofilm’s increased tolerance against antibiotics, disinfectants and the immune system [15], [18].
What is a major difference between cells in a biofilm and planktonic cells?
What is a major difference between cells in a biofilm and planktonic cells? Cells in a biofilm have a greater tolerance for antimicrobials. You just studied 19 terms!
Is saliva a biofilm?
Salivary biofilm, coating the surface of the restorative material, significantly decreased sucrose-dependent adhesion of Streptococcus sobrinus and Streptococcus mutans to the bleached and non-bleached surfaces, compared to non-coated specimens (p < 0.05). Saliva had a minor effect on adhesion of Actinomyces viscosus.
How are a slow spreading center and a fast spreading center different from each other?
How are a slow spreading center and a fast spreading center different from each other? Slow spreading centers tend to have developed rift valleys; fast spreading centers often lack rift valleys. Slow spreading centers have prominent ridges and rugged topography; fast spreading centers have rather smooth topographies.
What is turbulent flow quizlet?
Turbulent flow. -interrupted. -rate of flow exceeds critical velocity. -fluid responsible for heart sounds. -sounds due to turbulence not normal in arteries and is probably due to some constriction; increases the probability of thrombosis.
