What is co-current flow and countercurrent flow?
co-current flow means when two liquids let say A and B both move in same direction let say from right to left or vice versa. while counter current flow means both liquids move in opposite direction to each other for e.g. liquid A moves ffrom right to left and liquid B moves from left to right.
What is co-current mechanism?
Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other.
What is a co-current flow?
Co-current air flow, which is also referred to as parallel flow, occurs when the products of combustion flow in the same direction as the material. An organic combustion process commonly uses this air flow configuration, because it does not require a very specific end product.
Which is better co current or counter-current?
Overall, the counter-current heat exchanger is more efficient compared to the co-current heat exchanger, and is more widely used in the chemical process industry.
What are the two advantages of counter-current flow compared with co current flow?
One of the great advantages of counter-current flow is the possibility of extracting a higher proportion of the heat content of the heating fluid. It is important to note that the LMTD value for counter-current flow is much larger than for cocurrent flow at the same terminal temperature (see Figure 1.9).
Why is it called counter-current mechanism?
Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla. This passive process is known as countercurrent exchange.
Which is better co current or counter current?
Why is counter-current flow more efficient than co current flow?
In the counter flow setup, the fluids are travelling along the heat exchanger in opposite directions. This distributes the heat more evenly across the heat exchanger and allows for maximum efficiency.
Which is better co-current or counter-current?
Why counter-current is more efficient than co-current?
As a general choice, counter-current (or “counter-flow”) heat exchangers are more efficient because they poise the highest overall temperature differences across the process fluids. This is the goal of all heat transfer, to maximize temperature differences for the greatest amount of time in the process.
What are the two components of counter current mechanism?
There are two countercurrent mechanisms in the kidneys. They ‘re the loop of Henle and the vasa recta. Henle’s loop is a U-shaped part of the nephron.
