Fluid friction describes the friction … WebApr 6, 2024 · The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water …
WebJan 11, 2011 · When objects move through fluids, they have to overcome the friction acting on them, due to which they lose energy. So, efforts are made to minimize the friction. For this, the objects are... In order to reduce fluid friction, special forms have been designed to minimize the opposing frictional force acting on them. These unique shapes are termed as streamlined shapes which are pointed at the ends, to cut the fluid smoothly. See more The laws of fluid friction are: The rules hold differently for different lubricants. It is indirectly proportional to the temperature of the lubricant. The friction force is independent of the substances of the bearing surfaces as … See more Some of the examples of fluid friction are: The air particles that form up the air. It causes a falling object to slow down. The lubricants used in hinges. Submarine moving through water. It is external fluid friction that occurs on … See more The thinner the fluid, the lesser the fluid friction will be, and vice versa. For instance, water is thinner than honey. That is why there is less fluid friction in water than honey. See more Speed and friction are directly proportional to each other. The more the rate will be, the more the drag will be. For instance, a body moving with higher velocity will have more drag then a body moving with comparatively lesser … See more
