Which has less friction on a PVC pipe wood or metal?
PVC pipe has less friction. They are also longer lasting than the others.
What reduces friction between two pieces of metal?
Something with a low coefficient of friction such as PVC or PTFE polymers
What is coefficient of friction between water and PVC tube?
the coefficient of the tube change due to submergence
What is friction interaction?
Friction Interaction is a push or pull factor of your object rubbing against the ground.
Do tornadoes have friction?
Yes. Friction is always a factor. It is partly through drag, which can be thought of as friction, that the wind in a tornado is able to cause damage.
What factor does the limiting value of the force of the static friction depend?
limiting friction is force of friction when a body slides over the surface of another body
What does a strap wrench do?
used to loosen pipes (plumbing, pvc, etc) the rubber grips on the surface of large diameters, and friction loosens the tube.
What is the friction factor for smooth dry pavement?
The friction factor used in the Darcy-Weisbach equation to calculate the pressure drop in pipe flows is dependent on the surface roughness inside the pipe and Reynolds number of the pipe flow. The relationship between the friction factor and the relative roughness, Reynolds number can be found in the Moody diagram.
What factor prevents a machine from operating at 100 percent efficiency?
friction and other environmental forces ar responsible for <100 % efficiencies of machines.
What are the two factor that affect the friction force between two surfaces?
mass and velocity
How can you build a sled that goes further?
One way would be to reduce the friction factor.
What is the factor that slows a pendulum down and eventually causes it to stop?
That would be friction, both in the form of air resistance against the string and the weight, and friction at the pivot.
