2020-8-17Pressure is a measure of the force per unit area of resistance the pump can handle or overcome expressed in bar or psi (pounds per square inch) As in all centrifugal pumps the pressure in axial flow pumps varies based on the pumped fluid's specific gravity For this reason head is more commonly used to define pump energy in this way

2020-8-19Atmospheric pressure also known as barometric pressure (after the barometer) is the pressure within the atmosphere of Earth The standard atmosphere (symbol: atm) is a unit of pressure defined as 101 325 Pa (1 013 25 hPa 1 013 25 mbar) which is equivalent to 760 mm Hg 29 9212 inches Hg or 14 696 psi The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on

The ocean floor in particular is home to unique marine organisms as well as enormous geological features like volcanoes canyons and ridgelines In order to take full advantage of these opportunities for discovery scientists and explorers must first overcome one of the biggest challenges of deep ocean exploration: extreme pressure

Marine capture fisheries provide a valuable source of protein and are economically important in coastal communities However fisheries sustainability is impacted by incidental capture of nontarget species (bycatch) which remains a major global threat to marine megafauna such as sharks sea turtles seals cetaceans and seabirds Understanding where and when bycatch events take place can

2020-8-21Upper ocean stratification is assessed here (Figures 6-9) by sampling the model as Argo sampled the true ocean and then estimating mixed layer depth from those profiles by calculating the depth where the potential density exceeds the surface potential density by 0 3 kg m −3 Though differences are subtle it is often the case that when

2013-2-20Pressure is the compressive forceper unit area and it gives the impression of being a vector However pressure at any point in a fluid is the same in all directions That is it has magnitude but not a specific direction and thus it is a scalar quantity This can be demonstrated by considering a small

2020-5-13In this article you can get a clear picture on the boiler feed water pump that is multistage centrifugal pumps and type of seal used in it As the mechanical seals are normally used in the boiler feed water pump because it develops a high pressure as it has to feed the water to the boiler Along with this the procedure for dismantling and assembling of the boiler feed water pump and seal

A few different pressure sensor models have been used within Sea‐ CTD packages on board Argo floats Early floats contained pressure transducers manufactured either by Paine Corporation or Ametek Both models drifted toward anomalously high pressure values (positive pressure drift) of 5–10 dbar at the ocean surface [Barker et al 2011]

2019-10-11 Introduction The ocean contains numerous mineral and biological resources driving rapid development of marine exploration and exploitation in recent years (Urabe et al 2015 Girdhar and Dudek 2016) Deep-sea equipment an indispensable tool in underwater vehicles for conducting deep-sea scientific research and commercial resource exploration is continuously improved (Zhang et al 2017)

2007-10-2The seal must be pressured above the water injection Most seal vendors will suggest 25 to 30 psig or 2 bar above this for the Plan 53 or 54 system The bigger issue is then at what pressure should the water injection be This does rely upon what the box pressure would be during normal operaton and the reason you've installed a Plan 32 to begin

Dynamic O-ring Seal Obviously having a dynamic seal doesn't mean you can open a housing underwater However many times parts need to move while exposed to rain or under the sea So how do you ensure the container stays waterproof? Great news: it's just like the static seal but with less compression and more lubrication

SONAR Equation The "sonar equation" is a systematic way of estimating the expected signal-to-noise ratios for sonar (SOund Navigation And Ranging) systems The signal-to-noise ratio determines whether or not a sonar will be able to detect a signal in the presence of background noise in the ocean
