skin friction/surface friction drag — Drag caused by the unevenness in the skin of a body. The layers of air near the surface are retarded, and the speed of the airflow increases as the distance from the skin increases. To reduce the skin friction, the surface should be smoothened to … Aviation dictionary
Friction loss — refers to that portion of pressure lost by fluids while moving through a pipe, hose, or other limited space. Causes Friction loss has several causes, including:*Frictional losses depend on the conditions of flow and the physical properties of the … Wikipedia

Parasitic drag — (also called parasite drag) is drag caused by moving a solid object through a fluid. Parasitic drag is made up of many components, the most prominent being form drag. Skin friction and interference drag are also major components of parasitic drag … Wikipedia
Oceanic physical-biological process — Sea water is 827 times denser than air Due to the higher density of sea water (1,030 kg m 3) than air (1.2 kg m 3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore … Wikipedia
Leading edge slot — The leading edge slot is an aerodynamic feature of the wing of some airplanes to reduce the stall speed and promote good low speed handling qualities. A leading edge slot is a span wise gap in each wing, allowing air to flow from below the wing… … Wikipedia
