WebJul 24, 2024 · Hence, larger surface area does not in and of itself lead to larger drag. The streamlined body is designed to produce the low turbulence by balancing the fluid streamlines coming of the back of the body so that they have the same velocity on detaching and do not tend to collide with each other. WebMay 22, 2024 · A streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. The streamlined …

WebThey have compact, streamlined bodies, short wings, and very short tails. The feet are placed far back on the body, webbed, with no hind toe; claws are narrow and the tarsus is laterally compressed. The bill is variable in shape and may be highly ornamented in the breeding season. WebThe aerodynamic drag coefficient is a measure of the effectiveness of a streamline aerodynamic body shape in reducing the air resistance to the forward motion of a vehicle. A low drag coefficient implies that the streamline shape of the vehicle's body is such as to enable it to move easily through the surrounding viscous air with the minimum of …
