What else can I help you with?
When gases liquids or solids are in contact with a moving object the flow of occurs due to frictional forces?
The flow does not always change due to frictional forces when gases, liquids, or solids come in contact with a moving object. Often, the friction is caused by static friction.
What is the difference between bulk motion and diffusion?
The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê
Why do jet streams flow parallel to isobars?
Because jet streams are above the friction layer, they have a negligible effect. The wind is balanced by the Coriolis effect and the pressure gradient so that the winds flow parallel to isobars.
What is streamling?
the science of shaping objects to reduce drag so that fluids flow more easily around them
What is Bagnolds friction law?
Bagnold's law deals with fluid theory. It describes and predicts debris and granular flow down an incline by calculating shear rate.
How does friction help reduce scar tissue?
It increases blood flow.
What uses a cushion of air to reduce friction?
A hovercraft use a cushion of air to reduce friction. In extreme engineering applications there are also air bearings, bearings where a steady flow of air acts as a lubricant between two very finely machined surfaces to keep them apart.
Does streamlining produce more or less friction?
In general it means that there will be less surface friction on the material. On vehicles this can be done by reducing the impact area at the front and by integrating smooth curves for the air to follow. Surface polishing can also increase airflow and reduce friction.
What in electricity is like friction and tends to reduce the amount of current flow like buildup in a pipe reduces water flow?
Resistance inhibits current flow.
What type of technology is a hovercraft?
Hyperbaric flow control technology.
How does rubber soles reduce friction?
rubber has so much friction ,because it is appling static friction. 6th grade student
Flow does friction?
Friction acts as a resistance force that opposes the motion of fluids like water or air. When fluid molecules come into contact with a surface, friction causes them to slow down and stick, affecting the flow characteristics of the fluid. This can result in turbulence and energy loss within the system.
More friction between water and streambed will reduce the speed of flowing water?
Yes, increased friction between the water and the streambed will create resistance that slows down the flow of water. This can result in changes to the velocity and turbulence of the water flow.
Why is electrical resistance analogous to mechanical friction?
Electrical resistance is analogous to mechanical friction because both phenomena oppose the flow of energy in their respective systems. In electrical circuits, resistance limits the flow of electric current, while mechanical friction resists the motion of objects. Both contribute to energy loss in their systems and lead to inefficiencies.
Why are glidants added to drugs?
Glidants such as silicon dioxide help reduce the friction between particles and hence increase the flow of the tablet granules or powder.
How is the flow of air used in transportation?
Airplanes, Hovercraft's, Cars, Trucks, Helicopters........... Can go on forever....
What force opposes motion in fluids?
Viscosity is the force that opposes motion in fluids. It is a measure of a fluid's resistance to flow, and it arises due to internal friction between the molecules within the fluid.
