Knowledge of the streamlines can be useful in fluid dynamics. The curvature of a streamline is related to the pressure gradient acting perpendicular to the streamline. The center of curvature of the streamline lies in the direction of decreasing radial pressure. The magnitude of the radial pressure gradient can be calculated directly from the density of the fluid, the curvature of the streamline and the local velocity. WebStreamlined shape: A streamlined body is a shape that reduces friction drag between a fluid, such as air or water, and an object moving through it. Its particular body shape provides minimal resistance to air and water. The surface of airplanes and ships in the water has a streamlined shape to reduce fluid friction. Suggest Corrections 42

WebMay 17, 2024 · The most ideal shape of a submarine hull for minimum drag is the ideal streamlined shape with a parabolic bow and an elliptical stern, as shown in Figure 10. Figure 10: Ideal streamlined hull form. The first submarines in the 1940s used this shape for minimum power requirement and negligible flow separation around the hull. WebThe streamlines in a laminar flow follow the equation of continuity, i.e., Av = constant, where, A is the cross-sectional area of the fluid flow, and v is the velocity of the fluid at that point. Av is defined as the volume flux or the flow rate of the fluid, which remains constant for steady flow. When the area of the cross-section is greater ... WebAug 8, 2015 · A: A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. Drag is a force that slows down motion; friction drag is a special kind of drag. It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object’s motion. gas leaf blower mulcher combination
