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 ...

From Quanta Magazine (find original story here). Spaghetti-thin shoelaces, sturdy hawsers, silk cravats—all are routinely tied in knots. So too, physicists believe, are water, air and the liquid iron ...

Accurately monitoring the flow of fluids injected downhole to enhance oil recovery is critical for improving the efficiency of reservoir production methods. Current software uses streamline ...

The trade-offs necessary to choose a fluid involve a consideration of application requirements such as health, safety, and environmental effects, and fluid properties such as viscosity, stability, ...

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 ...

Current drilling and fracturing methods can't extract oil and natural gas very well, recovering an estimated 5 percent of oil and 20 percent of gas from shale. That's partly due to a poor ...
