How can fluid friction be minimised
WebDrag is the resistance that water exerts on your body as you move through it. There are two phases of drag, known as passive drag and active drag. Passive drag is the resistance a swimmer meets while swimming … WebFriction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction …

Web16 de mai. de 2024 · Dry friction can be subdivided into static friction (“stiction”) between immobile surfaces, and kinetic friction which operates between moving surfaces. With the exception of atomic or molecular friction, dry friction generally occurs due to the interaction of surface features, which are termed as asperities. Fluid friction is the friction ... WebOne fluid showed strong oscillations in the extension force, with frequency peaks at around 50, 100 and 150 Hz. Analysis of the sound spectrum showed peaks corresponding to the force oscillations. A second fluid, which contained a friction modifier, showed almost no force oscillations under the same conditions.
WebIt is obvious that when objects move through fluids, they have to overcome the friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimize the friction. So objects are given special shapes. WebFluid friction can be minimized bya)Adding salts to fluidb)Increasing volumec)Giving suitable shaped)Decreasing volumeCorrect answer is option 'C'. Can you explain this …
Web6 de abr. de 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 … WebAnswer (1 of 2): Form drag is essentially as a result of the entirety of the frontal surface area of the aircraft. The reason it causes drag is because the air cannot pass directly through it. When air hits the aircraft, it is pushed around it, but it …
WebTo minimize friction, one of two things could happen: Normal force could be minimized, or the coefficient of static/kinetic friction could be minimized. In a lot of real-world scenarios, however, it is hard to minimize the normal force between two objects, and so minimizing the coefficient of static/kinetic friction is important.
