In addition, as the video points out, fluid flow in a pipe is very similar to electrical current flowing through wires. The discussion about friction loss coves some math, but we were surprised ...

From pumping hearts to revving engines, flaps help fluid flow in one direction ... These flexible pipe designs, which are better mimics for shark intestines through both their "deformability ...

For instance, in the flow through a large duct where the boundary layers are very thin, viscous effects are confined to a rather small region, and the fluid friction may sometimes be neglected. This ...
