Driving force An experiment has confirmed that an oscillating temperature gradient boosts heat flow in fluids. (Courtesy: iStock/Mervana) Physicists in the Czech Republic have shown that heat flows ...
A full-scale, closed-loop bioreactor (Orbal oxidation ditch, Envirex brand technologies, Siemens, Waukesha, Wisconsin), previously examined for simultaneous biological nutrient removal (SBNR), was ...
A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...
