Whether it's water flowing across a condenser plate in an industrial plant, or air whooshing through heating and cooling ducts, the flow of fluid across flat surfaces is a phenomenon at the heart of ...

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 ...

Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter ...

For most fluids, an increase in pressure should lead to a burst of speed, like squeezing ketchup from a tube. But when flowing through porous materials such as soil or sedimentary rock, certain ...

It's a common misconception that fluids with different flow rate requirements always need separate pumps. In reality, that's not necessarily the case. Image Credit: Fluid Metering, Inc. When working ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

Water makes up around 60% of the human body. More than half of this water is inside the cells that make up organs and tissues, and much of the remaining water flows in the spaces between cells. MIT ...
