Energy lost due to friction

WebA small amount of the energy is lost due to friction, which is why it's impossible for a roller coaster to return to its original height after the ride is over. The roller coaster uses a motorized lift system to return to its original position at the top of the initial hill, ready for the next ride. The figure below illustrates the concept. WebEnergy loss in pipes due to friction. When a fluid travels in a pipe energy is dissipated by friction. The amount of energy lost depends on a number of factors such as the fluid’s speed and viscosity. If the flow is turbulent it can even depend on …
