Poiseuille's law describes the flow rate of a fluid through a cylindrical tube. It states that the flow rate is directly proportional to the pressure difference across the tube and the fourth power of the tube radius, and inversely proportional to the viscosity of the fluid and the length of the tube. Mathematically, it can be expressed as Q = πΔP r^4 / (8ηL), where Q is the flow rate, ΔP is the pressure difference, r is the radius, η is the viscosity, and L is the length of the tube.

What is poiseuilles law when pressure drops?
Poiseuille's law states that the rate of flow of a fluid through a tube is directly proportional to the pressure difference along the tube. When pressure drops, the flow rate will increase accordingly if all other factors remain constant. This relationship highlights the importance of pressure in influencing fluid flow dynamics.

Which law of motion is used to explain rocket propulsion?
The third law of motion, known as Newton's third law, is used to explain rocket propulsion. This law states that for every action, there is an equal and opposite reaction. In the case of a rocket, hot gases are expelled backward, causing the rocket to move forward in the opposite direction.
What is the purpose of newton third law of motion?
The purpose of Newton's third law of motion is to explain how forces interact between two objects. It states that for every action, there is an equal and opposite reaction, which means that when one object exerts a force on another object, the second object will exert an equal force in the opposite direction. This law helps explain the concept of force pairs and how motion is influenced by these interactions.
Is the scientific law explain why something happens?
No, scientific laws describe what happens under certain conditions, based on repeated observations and experiments. They do not explain why things happen, but provide a framework for understanding and predicting natural phenomena.
What is poiseuilles law?
Q= (pi R^4(p1-p2))/(8n L) = cm^3/sec
How do you explain the law of variable proportion?

Find a formula for Poiseuilles Law given that the rate of flow is proportional to the fourth power of the radius and Use k as the proportionality constant?
Rate of flow varies as R^4 where R is the radius or Rate of flow = (k) x (R^4)
Which physical parameters the flow rate of a viscous liquid depends on using poiseuilles law?
According to Poiseuille's law the following factors effect the flow rate of a liquid in a tube: -* Internal radius of the tube, R* The pressure difference between ends of the tube, delta P* The Viscosity n of the fluid.* The length of the tube.
Explain what cause a law to become untrue?
A law that is not done right is a law that is untrue. This is usually when a law that was not passed.

What is an example of how one law could explain all motion in the unverse?
Newton's F=ma is an example of a law that could explain all motion in the universe.
