Poiseuille's law

Poiseuille’s law describes how fluids flow through a tube. It states that the flow rate increases with higher pressure and larger tube radius, while it decreases with greater fluid viscosity. This means that for a given pressure, thicker fluids flow more slowly, and wider tubes allow more fluid to pass through than narrower ones. Essentially, it helps us understand the factors that influence how easily liquids move in pipelines or blood in vessels, highlighting the balance between pressure, tube size, and fluid characteristics in determining flow behavior.
