Final answer:
Poiseuille's law, also known as the Young-Laplace equation or Jurin's law, describes the flow of a fluid through a capillary tube. It states that the flow rate Q is directly proportional to the pressure difference across the tube and the fourth power of the radius of the tube, and inversely proportional to the viscosity of the fluid and the length of the tube.
Step-by-step explanation:
Poiseuille's law, also known as the Young-Laplace equation or Jurin's law, describes the flow of a fluid through a capillary tube. It states that the flow rate Q is directly proportional to the pressure difference across the tube and the fourth power of the radius of the tube, and inversely proportional to the viscosity of the fluid and the length of the tube. Mathematically, it can be expressed as:
Q = (π * ΔP * r^4) / (8 * η * L)
Where Q is the flow rate, ΔP is the pressure difference, r is the radius of the tube, η is the viscosity of the fluid, and L is the length of the tube.
