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 ...
Such an event is often called a bubble, by analogy with an air bubble in a fluid pipe. In some architectures, the execution stage of the pipeline must always be performing an action at every cycle. In that case, the bubble is implemented by feeding NOP ("no operation") instructions to the execution stage, until the bubble is flushed past it.
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 the field, oil is moved through pipelines from about 1000 wells, to a pumping station at the head of the Trans-Alaska Pipeline; "flow lines" carry oil from the wells to local processing centers where the oil is prepared for long-range transport through the pipeline by removing water and gas; "transit lines" then carry the oil to the pumping ...
Petroleum products are transported via rail cars, trucks, tanker vessels, and pipeline networks. The method used to move the petroleum products depends on the volume that is being moved and its destination. Even the modes of transportation on land such as pipeline or rail have their own strengths and weaknesses.
Southern California's water district installs a quake-resistant pipe along the Colorado River Aqueduct to prevent a major spill.
The most common leak detection method for pipeline operators is called the Supervisory Control And Data Acquisition (SCADA) system. This system uses a series of sensors to track data such as pressure, flow rates, temperature, and whether valves are open or closed.
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
