A submarine is not streamlined primarily because its design prioritizes buoyancy and structural integrity over hydrodynamic efficiency. Unlike streamlined objects that minimize drag, submarines have a robust hull to withstand water pressure at depth and accommodate various systems, including ballast tanks and propellers. Additionally, the need for features like hatches and periscopes creates protrusions that disrupt a streamlined shape. Consequently, while submarines are designed to be efficient underwater, their form is not optimized for streamlining in the same way as fast-moving aquatic animals or streamlined vehicles.
Both have a similar shape that is streamlined, and both use "wings" (planes in submarine terrms) to adjust their movement as they're propelled through their respective mediums (air and water).
A submarine travels faster submerged than on the surface primarily due to reduced drag. When submerged, the submarine displaces water instead of having to contend with the surface tension and turbulence of waves, which can slow it down. Additionally, operating underwater allows for a streamlined hull design that minimizes resistance. This combination enables submarines to achieve higher speeds when submerged.
whats a streamlined?
The dimensions of a submarine can vary widely depending on its type and purpose. For example, a typical military attack submarine like the U.S. Navy's Virginia-class is about 377 feet long and approximately 34 feet wide, with a displacement of around 7,800 tons when submerged. In contrast, smaller research submarines may be significantly shorter and lighter. Overall, submarines are designed to be streamlined for underwater navigation and can range from small manned submersibles to large military vessels.
wATER BEING STREAMLINED.
Streamlined often means aerodynamic.
penguin is streamlined to swim in cold waters
Yes it does it has a streamlined body
uTorrent is a streamlined torrent download program.
Their shape and aerodynamic efficiency makes them streamlined.
You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
It was obvious he'd merely streamlined my report! Won't today's jets fly faster if they become more streamlined? This team will operate much more efficiently after I've streamlined it.
