Pickwick in saying this, and moreover muttered in an excited fashion certain unpleasant invocations concerning his own eyes, limbs, and circulating fluids
, the latter gentleman deemed it advisable to pursue the discourse no further.
However, the permeability reduction resulting from quartz precipitation in rocks with a primary porosity of 0.025 slows fluid circulation near the intrusion and thereby allows a greater fraction of circulating fluid
to be heated to supercritical temperatures (Figure 9(c)).
The other problem with glycol is called "stagnation," where in a system that is not constantly circulating fluid
during daylight hours, heat inside the collector can reach 400 to 600[degrees]F which can degrade the glycol mixture over time.
Later, it can heat or cool the circulating fluid
as necessary to maintain the correct temperature.
The chemicals used to adjust water quality for these larger systems are often not acceptable for use when the circulating fluid
is also connected to a ground loop.
Electric heaters are commonly used to inject heat into the ground by heating the circulating fluid
. The heated fluid is circulated through the borehole for 2-3 days.
Also, Acuna (2010) discussed an annular prototype in which temperature differences between the borehole wall and the circulating fluid
are measured to be very low.
The main consumers of current are the electrical pump that drives the hydraulic system, electrical heating and the temperature control of circulating fluid
Other causes include dehydration (less circulating fluid
equals a higher calcium concentration) as well as long-time overuse of vitamin A and D supplements.
Around the ice is circulating fluid
- its temperature controlled to 1/100th of a degree Celsius - that keeps the ice at its melting point so it slides on a thin film of water.
Outotec's delivery covers the engineering, supply and construction of a circulating fluid
bed calcination plant with a capacity of 1,600 tons of alumina per day.
Geoexchange piping systems are frequently classified as "closed-loop" or "open-loop." Closed-loop systems may be vertical or horizontal, and are fully encased in pipe so that the circulating fluid
does not contact soil or rock.
