BIO325H5 Lecture Notes - Lecture 15: Volumetric Flow Rate, Seta, Paddlefish
Document Summary
Having a big one could help with an organisms sessile lifestyle and hiding away the filter when necessary: predation. They will have specialized brain parts that will retract the filter in a super fast burst: environmental sensitivity. Other environments are toxic and can effect filter feeders since they adapted to the one they live in. Shear-gradient: when a viscous material goes across an object and it sticks and creates a gradiento lower re = thicker gradient. No slip condition: when fluid adjacent to a solid does not move with the current. The velocity gets higher the higher you go and this is where the black flies live. Boundary layer: when the proximity of the bottom is affecting the water speed (90% difference) Faster the flow = thinner gradient/boundary layer = steeper the gradient. Viscous entertainment: when the water hits the lower part of the black fly larva and travels up the body to the fans.
