Computer simulations help materials scientists and biochemists study the motion of macromolecules, advancing the development ...

Flow through a hollow needle is characterized by the Hagen-Poiseuille equation: Although syringe plunger friction and tissue resistance at the needle tip will add to syringe plunger force, viscous ...

The force acting on a body due to the viscous resistance of the surrounding fluid is called the drag force and it acts in the direction opposite to the direction of motion. As a consequence of the ...

A University of Oregon graduate student has developed a new mathematical equation that ... calculate the friction biomolecules experience within their chaotic, viscous environment.

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very ... and a ...
