### Physics 115A - University of Washington

A string of undersea oceanographic instruments is held down by an anchor, and pulled upright by a hollow steel sphere float. The float displaces 1 m3 of seawater It weighs 1000N when in air What upward force can it supply to hold up the string? 4/4/14 Physics 115 3 F g =m STEEL g=1000N B= SEAWATER gV FLOAT Standard Pipe Dimensions - archtoolboxMay 23, 2021 · Nominal Pipe Size (abbreviated NPS) is a North American standard for identifying pipe sizes. Technically, the NPS is non-dimensional and only roughly refers to the diameter of the pipe. However, from NPS 14 and above, the NPS value matches the outside diameter of the pipe. Nominal Pipe Sizes apply to all materials of pipe. The Mathematics of Pumping Water - RAEngWe can calculate the velocity in pipe using the following formula:A Q v = (4) where Q = flow rate through the pipe (m 3 /sec) A = pipe cross s ectional area (CSA) (m 2 ) If Q is 2500 m 3 /hr and the flow is pumped through a 0.8 m diameter pipe then:0 . 5 4 0 . 8 4 2 f2 = =

### The Pluto Pipeline International Marine Consultancy

Nov 05, 2008 · The second type was a less flexible steel pipe of similar diameter, developed by engineers from the Iraq Petroleum Company and the Burmah Oil Company, known as HAMEL from the contraction of the two chief engineers, HA Hammick and BJ Ellis. It was discovered in testing that the HAMEL pipe was best used with final sections of HAIS pipe each end. This document was downloaded from the Penspen Company had over 54,000 yards (49km) of wooden pipe and 1,800 yards (1.6km) of cast iron. The use of wood, iron, lead, and tin pipes were common into the 1800s to transport water, and in 1821 wood pipe transported natural gas in New York State, USA.

### Wet insulation evolves to meet subsea flowline performance

Oct 01, 2008 · According to Watkins, Cumings first wet pipe insulation products were intended for use down to 1,000 m (3,281 ft), while current materials are suitable for use at 2,000 m (6,562 ft), and a third-generation insulation under development will be rated for 3,000 m (9,842 ft). X65 steel pipeline successfully laid in China deepwater Jun 15, 2020 · On May 23, 2020, the sea pipeline of the Lingshui 17-2 project, China's first deepwater gas field, was successfully laid at 1,532 meters, breaking China's new record for sea pipeline laying and the first operation at 1,500 meters of "ultra-deepwater". The project used more than 10,000 tons of undersea steel pipeline from Henggang, Hunan province.
