Air lock problems often occur when one is trying to recommission a system after it has been deliberately (for servicing) or accidentally emptied. Take, for example, a central heating system using a circulating pump to pump water through radiators. When filling such a system, air is trapped in the radiators. This air has to be vented using screw ...
This mechanism is found very commonly in everyday life, including central heating and air conditioning and in many other machines. Forced convection is often encountered by engineers designing or analyzing heat exchangers, pipe flow, and flow over a plate at a different temperature than the stream (the case of a shuttle wing during re-entry, for example).
January 21, 2019 - A 30-inch diameter natural gas pipeline owned by Enbridge exploded in Noble County, Ohio at approximately 10:40 a.m.. The pipeline was built in the 1950s, and last inspected in the 1980s prior to the explosion. Still under investigation, corrosion is the presumed cause. [119]
2010: Dalian Pipeline disaster – The explosion of two petroleum pipelines and subsequent fire in the port of Dalian, in northern China's Liaoning province on Saturday, on July 17, 2010, caused fatalities, damages and an ecological disaster, releasing 11,000 barrels of oil into the Yellow Sea, and covering up, according to different sources, from 50 to 430 km 2 of sea and coast lines.
In fluid mechanics, pipe flow is a type of fluid flow within a closed conduit, such as a pipe, duct or tube. It is also called as Internal flow. [1] The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect.
Sandblasting nozzles accelerate and air and media mixture; Bilge water can be emptied from a moving boat through a small waste gate in the hull. The air pressure inside the moving boat is greater than the water sliding by beneath. A scuba diving regulator uses the Venturi effect to assist maintaining the flow of gas once it starts flowing
Southern California's water district installs a quake-resistant pipe along the Colorado River Aqueduct to prevent a major spill.
A common example of multiphase flow in industry is a fluidized bed. This device combines a solid-liquid mixture and causes it to move like a fluid. [15] Further examples include water electrolysis, [16] bubbly flow in nuclear reactors, gas-particle flow in combustion reactors and fiber suspension flows within the pulp and paper industry. [17]
