Seymour Narrows
Seymour Narrows is a section of the Discovery Passage in British Columbia known for strong tidal currents. Discovery Passage lies between Vancouver Island at Menzies Bay, British Columbia and Quadra Island except at its northern end where the eastern shoreline is Sonora Island. The section known as Seymour Narrows begins about from the south end of Discovery Passage where it enters the Georgia Strait near Campbell River. For most of the length of the narrows, the channel is about wide. Through this narrow channel, currents can reach . Etymology The narrows were named for Rear Admiral Sir George Francis Seymour who commanded the Pacific Station from 1844 to 1848. Seymour Narrows was described by Captain George Vancouver as "one of the vilest stretches of water in the world." Even after Ripple Rock was removed, it remains a challenging route. In March 1981, the freighter ''Star Philippine'' ran aground in the narrows. Hydrology Seymour Narrows is notable also because the f ...

Discovery Islands
The Discovery Islands are a group of islands located at the northern end of the Salish Sea and the eastern end of Johnstone Strait, between Vancouver Island and the mainland coast of British Columbia, Canada. Most of these islands have very few residents. Only Quadra Island and Cortes Island have ferry service. The remainder are served by private boat or float plane. Geography The area's complex geography can make it difficult to determine when travelling by boat whether a sighted coastline belongs to the mainland, Vancouver Island, or one of the Discovery Islands. Major islands The Discovery Islands are all located within the Strathcona Regional District, except for a few of the southernmost, such as Hernando Island and Savary Island, which are in the qathet Regional District. The larger islands within the Discovery Islands are: ; Strathcona Regional District * Cortes Island (west: Subtle Islands) * Hardwicke Island (north: Poyntz, Seymour, Murray; west: Yorke; sou ...

Reynolds Number
In fluid dynamics, the Reynolds number () is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between Inertia, inertial and viscous forces. At low Reynolds numbers, flows tend to be dominated by laminar flow, laminar (sheet-like) flow, while at high Reynolds numbers, flows tend to be turbulence, turbulent. The turbulence results from differences in the fluid's speed and direction, which may sometimes intersect or even move counter to the overall direction of the flow (Eddy (fluid dynamics), eddy currents). These eddy currents begin to churn the flow, using up energy in the process, which for liquids increases the chances of cavitation. The Reynolds number has wide applications, ranging from liquid flow in a pipe to the passage of air over an aircraft wing. It is used to predict the transition from laminar–turbulent transition, laminar to turbulent flow and is used in the scaling of similar but different-sized fl ...

Central Coast Of British Columbia
The British Columbia Coast, popularly referred to as the BC Coast or simply the Coast, is a geographic region of the Provinces and territories of Canada, Canadian province of British Columbia. As the entire western continental coastline of Canada along the Pacific Ocean is in the province, it is synonymous with being the West Coast of Canada. While the exact boundaries are variously defined, the region is generally defined to include the 15 regional districts that have coastline along the Pacific Ocean or Salish Sea, or are part of the Lower Mainland, a subregion of the British Columbia Coast. Other boundaries may exclude parts of or even entire regional districts, such as those of the aforementioned ''Lower Mainland''. Boundaries While the term ''British Columbia Coast'' has been recorded from the earliest period of non-native settlement in British Columbia, it has never been officially defined in legal terms. The term has historically been in popular usage for over a century to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Halifax Explosion
On the morning of 6 December 1917, the French cargo ship collided with the Norwegian vessel in the harbour of Halifax, Nova Scotia, Canada. ''Mont-Blanc'', laden with Explosive material, high explosives, caught fire and exploded, devastating the Richmond, Nova Scotia, Richmond district of Halifax. At least 1,782 people, largely in Halifax and Dartmouth, Nova Scotia, Dartmouth, were killed by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the Largest artificial non-nuclear explosions#Largest accidental artificial non-nuclear explosions by magnitude, largest human-made explosion at the time. It released the equivalent energy of roughly . ''Mont-Blanc'' was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux, France. At roughly 8:45 am, she collided at low speed, approximately one knot (), with the unladen ''Imo'', chartered by the Commission for Relief in Belgi ...

Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate ar ...

Nitramex
Nitramex and Nitramon Explosives are compositions of various chemical compounds. They are explosives based on ammonium nitrate, with other ingredients such as paraffin wax, aluminum and dinitrotoluene. The inclusion of these additional ingredients creates a more stable explosive. Nitramex and Nitramon have in modern times been replaced by more advanced high explosives based on ammonium nitrate, such as ANFO. Nitramon A typical nitramon formula contains approximately 92 percent ammonium nitrate, 4 percent dinitrotoluene and 4 percent paraffin wax. Nitramon is insensitive to shock, friction, flame and impact. It can't be detonated by blasting cap and requires booster to set it off. Different grades of Nitramon were produced, including S and WW for seismic exploration and HH for blasting in high temperature environments, like coal-seam fires. Nitramex Nitramex has much the same formula as nitramon but with the addition of trinitrotoluene (TNT). It has higher density and explosive ...

USS Saranac (1848)
USS ''Saranac'' was a sloop-of-war of the United States Navy. The ship laid down in 1847 during the Mexican–American War; however, by the time she completed sea trials, the war was over. She was commissioned in 1850 and saw service protecting American interests in the Atlantic Ocean as well as the Pacific Ocean. When the American Civil War broke out, ''Saranac'' patrolled America’s West Coast. Retained by the Navy post-war, she continued in service until wrecked on Vancouver Island, British Columbia in 1875. Construction The second ship to be so named, ''Saranac'' was laid down in 1847 by the Portsmouth Navy Yard, and was launched on 14 November 1848. The new side-wheel steam sloop of war got underway on 10 April 1850 for a trial cruise in the North Atlantic. Upon returning home, she underwent repairs and alterations before commissioning on 12 October 1850, Captain Josiah Tattnall III in command. Early operations ''Saranac'' operated along the Atlantic coast of the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
