Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...
The dry-looking stream in your backyard may play a major role in feeding U.S. rivers. Channels that flow only in direct response to weather conditions like heavy rain, called ephemeral streams, on ...
A new study has mapped 35 years of river changes on a global scale. The work has revealed significant effects on both downstream (44% decrease in water flow) and upstream (17% flow increase) rivers, ...
When two materials come into contact, charged entities on their surfaces get a little nudge. This is how rubbing a balloon on the skin creates static electricity. Likewise, water flowing over some ...
Higher flow velocities lead to better water quality by increasing residual disinfectants and reducing microbial activity and nitrification Smaller diameter pipes (3/8") benefit most from high flow ...
IDENTIFY THE OTHERS INVOLVED. A CONSERVATION GROUP IS CONCERNED ABOUT LOW WATER FLOW ALONG THE WEKIVA RIVER, THEY SAY COULD THREATEN THE ECOSYSTEM. WESH 2’S TONY ATKINS EXPLAINS THE FACTORS AT PLAY ...
