Laminar and Turbulent Flow01:07

Laminar and Turbulent Flow

8.5K
Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Fluids can be classified into Newtonian and non-Newtonian fluids based on their response to shear stress. Newtonian fluids have a linear relationship between shear stress and the shear strain rate, following Newton's law of viscosity. Their viscosity remains constant regardless of the shear rate, making their behavior predictable and easier to analyze. Common examples include water, air, oil, and gasoline.
In contrast, non-Newtonian fluids do not follow Newton's law of viscosity, and...

Fluid Movement Between Compartments

The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Introduction to Types of Flows

1.2K
Fluid flows are categorized by dimensionality and behavior, with one-dimensional flow being the simplest form, where properties like velocity and pressure change only along a single axis. Water moving through straight pipes exemplifies this flow type, as variations in other directions are minimal. One-dimensional analysis helps simplify understanding such flows, focusing solely on changes along the pipe's length.
Two-dimensional flow involves changes in both length and height, as seen in...

Viscosity

5.8K
When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.
The SI unit of viscosity is...

Area of Science:

  • Physiology
  • Neuroscience
  • Behavioral Science

Background:

  • Water balance is vital for survival, with thirst driving fluid intake.
  • Overconsumption of water can be harmful, necessitating a balance between thirst and satiety.
  • Understanding the complex regulation of thirst and water intake is essential for maintaining homeostasis.

Purpose of the Study:

  • To review current knowledge on thirst generation and quenching.
  • To highlight the roles of angiotensin II, glucagon-like peptide 1, and estradiol in regulating thirst.
  • To present a framework for understanding the transitions between thirst and satiety states.

Main Methods:

  • Literature review synthesizing existing research on water intake regulation.
  • Analysis of modern behavioral studies with high temporal resolution of intake patterns.
  • Examination of the influence of specific bioregulators on thirst and satiety.

Main Results:

  • Thirst is directly driven by fluid intake disruptions and modulated by bioregulators.
  • Angiotensin II, glucagon-like peptide 1, and estradiol play key roles in modulating thirst.
  • Advanced behavioral analysis reveals intricate patterns in water intake, moving beyond simple stimulatory/satiety models.

Conclusions:

  • A comprehensive framework is proposed for understanding thirst regulation.
  • Further research is needed to fully elucidate the system's transitions between thirst and satiety.
  • Integrating bioregulator roles with fluid intake dynamics offers a more nuanced view of water balance control.
