The energy lost through friction as a fluid flows through a pipe. The amount of energy lost is dependent on both the characteristics of the fluid (viscosity, density) and the pipe (roughness, diameter, length) as well as the rate of flow.
What else can I help you with?
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
On what does the frictional force depend?
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.
Is frictional force desirable?
Yes it is desirable to some extent. For sure aeroplanes can't fly without moving on the ground (Frictional Force). Even a ship cannot move without friction. For erasing a mistake, the rubber has to show friction with the paper. But due to friction, there is a huge amount of energy is wasted. One way to discriminate it is: People can get injured themselves if they rub their hands hard on floors or sharp items.
What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
What is the losses of three phase induction motors?
Iron Loss Copper Loss Frictional loss
Why machine parts oil occasionally?
to reduce the energy loss due to frictional force.
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
When was Frictional Games created?
Frictional Games was created in 2006.
What is Frictional Games's population?
Frictional Games's population is 8.
What are the limitations of frictional force?
Frictional force depends on the nature of the surfaces in contact and can vary based on surface roughness, temperature, and the presence of lubricants. It does not depend on the surface area in contact but relies on the normal force acting between the surfaces. Frictional force can also generate heat and wear on the surfaces in contact, leading to energy loss and decreased efficiency in mechanical systems.
What is the frictional force needed to slow an object in motion.?
kinetic frictional
Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
How do you define term frictional electricity?
Frictional electricity is a static electrical charge.
