The Tesla valve is a passive check valve with no moving parts. Because it has no moving parts, there is less wear and tear while reducing the risk of clogging. In general, the resistance to flow in ...

As an important liquid transportation equipment, vehicle mounted self-priming pumps have been widely used in various fields such as chemical, petroleum, fire protection, and agricultural irrigation.

This teaching package covers fluid kinematics topics. It includes description of fluid motion, introducing different co-ordinate systems used to mathematically calculate fluid flow behaviors and ...

Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley. Some material in this section may seem self-evident ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

Scientific progress is not usually straightforward. Researchers pursue and abandon lines of inquiry. Results languish. Theories take decades to cohere. But sometimes the accumulation of scientific ...

Controlling the flow Vortex-induced heat backflow (top) in a simulated 2D graphite strip, compared with conventional heat flow (bottom). (Courtesy: 2026 THEOS EPFL CC BY SA) We are all familiar with ...
