What is the stokes law explain?

What is the stokes law explain? Stoke’s Law states that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of the sphere, and the viscosity of the fluid.

What is stokes law and prove it? Stokes’ law is a law in physics that states that the force that resists a sphere’s fall in a viscous fluid is directly proportional to the velocity of the sphere, the radius of the sphere, and the viscosity of the fluid.

What is stokes law derive its formula? This retarding force acting on a body as it passes through a viscous fluid is directly proportional to the sphere’s velocity, radius, and fluid viscosity. This is Stokes law. This equation of Stokes Law can be given as, (F = 6 πηrv).

What is stokes law and terminal velocity? Solution : According to stokes law, the backward viscous force acting on a small spherical body of radius r moving with velocity v through fluid of viscosity `eta`is given by ` F = 6 x eta r v`. Terminal velocity is the maximum Uniform velocity of the spherical body moving in a fluid.

What is the stokes law explain? – Additional Questions

What do you mean by Stokes law in laminar flow?

Stokes Law, named after George Gabriel Stokes, describes the relationship between the frictional force of a sphere moving in a liquid and other quantities (such as particle radius and velocity of the particle).

What terminal velocity means?

Definition of terminal velocity

: the limiting uniform velocity attained by a falling body when the resistance of the air has become equal to the force of gravity.

Do heavier objects fall faster?

Moreover, given two objects of the same shape and material, the heavier (larger) one will fall faster because the ratio of drag force to gravitational force decreases as the size of the object increases.

What is the fastest an object can fall?

Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph) for a human skydiver.

How fast does a bullet fall from the air?

When you fire a bullet into the air, it typically takes between 20 and 90 seconds for it to come down, depending on the angle it was fired at, its muzzle velocity and its caliber.

Can you dodge a bullet?

Bullet dodging, Scientific American reports, is one such make-believe ability invented by Hollywood. Regardless of your speed and finesse, no human can dodge a bullet at close range. The bullet is simply traveling too fast. Even the slowest handguns shoot a bullet at 760 miles per hour, SciAm explains.

Can a bullet go through a roof?

Bullets often lodge in roofs, causing minor damage that requires repair in most cases. Normally, the bullet will penetrate the roof surface through to the roof deck, leaving a hole where water may run into the building and cause a leak.

Can you leave bullets in your body?

This week new data from the CDC warns us that bullet fragments left inside of people can have insidious long-term consequences, from fatigue to memory loss to mood disorders to miscarriage.

Is it better for a bullet to go through or stay in?

A bullet that passes through the body (creating an exit wound) generally will cause less damage than one which stays in the body, because a bullet that stays in the body transfers all of its kinetic energy (and ensures maximum damage to tissue).

Do bullet wounds leave scars?

You may have bullet pieces that remain in your body. Often these cannot be removed without causing more damage. Scar tissue will form around these remaining pieces, which may cause ongoing pain or other discomfort. You may have an open wound or a closed wound, depending on your injury.

Why do you need to take a bullet out?

A bullet is lead, so if it is in the body, it will leak lead into the body, which gets into the bloodstream. Side effects are bound to happen in time from the exposure. Despite the new research, many still feel leaving the bullet is the best solution.

Why would a doctor not remove a bullet?

In most cases, if a bullet has not penetrated an internal organ or caused infection, doctors will leave it in rather than risk surgery. The surrounding tissue encapsulates the bullet, preventing it from dissolving and leaching into the blood.

What happens when a bullet stays in the body?

Doctors have generally considered it safer to leave the metal inside bodies, unless they caused an infection or were stuck in a major organ, artery or joint. To dig the metal out risked causing extensive bleeding and scarring, and potentially damaging muscles and tissues.

Can a bullet left in your body cause lead poisoning?

Lead intoxication (saturnism) caused by bullets or projectiles lodged in the human body is an under-diagnosed condition, that can be fatal if not recognized 1 3 . Projectiles lodged in the joints or pseudo-cysts are more likely to develop this complication due to contact with synovial fluid.

What does a bullet taste like?

Medium amber in color, with gentle spiciness and sweet oak aromas. Mid-palate is smooth with tones of maple, oak, and nutmeg. Finish is long, dry, and satiny with a light toffee flavor.”

Do lead bullets dissolve in water?

Lead metal is unstable when it is in contact with air and water. It corrodes and forms hydrocerrussite, the white coating seen on old bullets in museums.

Does gunpowder contain lead?

Lead is found in bullets as well as the explosive that ignites gunpowder.
