LVF Liquid volume fraction is the ratio of the liquid volumetric flow rate to the total volumetric flow rate.

It is defined as formula_1where formula_2 is the liquid phase mass flow rate formula_3 is the gas phase mass flow rate formula_4 is the gas density formula_5 is the liquid density.

Venous return is the rate of blood flow back to the heart.

Also, the perpetuity growth rate assumes that free cash flow will continue to grow at a constant rate into perpetuity.

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature.

It's nitrogen narcosis.

This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g.

The efficacy of a carbon filter is also based upon the flow rate regulation.

In either case, the aim is to produce nitrogen gas, rather than nitrogen oxides.

Nitrogen fixation by cyanobacteria in coral reefs can fix twice the amount of nitrogen than on land around 1.8 kg of nitrogen is fixed per hectare per day.

Nitric oxide, or nitrogen oxide, also known as nitrogen monoxide, is a molecule with the chemical formula NO.

Lighter isotopes of nitrogen are preferred in the reaction, leaving the heavier nitrogen isotopes in the residual matter.

The mean annual flow rate of the Congo River at Inga Falls is 42,000 cubic metres per second.

Ammonia nitrogen was removed via nitrification denitrification up to 40 when nitrogen loading rates were of 0.18 kg N (m3 d).

In chemistry, N represents the element nitrogen.

Ocean currents are measured in sverdrup (sv), where 1 sv is equivalent to a volume flow rate of per second.

The RMS velocities of diatomic nitrogen and oxygen are very similar and thus no change occurs in the ratio of oxygen to nitrogen.

Starting at the intersection of the distillate composition line and the x y line, draw the rectifying operating line at a downward slope (Δy Δx) of L (D L) where L is the molar flow rate of reflux and D is the molar flow rate of the distillate product.

The equilibrium rotation rate varies directly with the flow velocity and inversely with the distance between the magnet and the duct.

) This is typically done with chlorine and nitrogen gas.

An analogous process for organic nitrogen compounds is deamination.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

However, an excited state zwitterionic isomer exists in which H is transferred from the oxygen (giving an oxygen anion) to the nitrogen (giving a protonated nitrogen cation).

The population is aging at an accelerating rate, and the net flow of working age citizens into the labor force has turned negative.

The ideal flow rate is roughly 8 liters of solvent per kilogram of garments per minute, depending on the size of the machine.

The Dearman engine differs from former nitrogen engine designs in that the nitrogen is heated by combining it with the heat exchange fluid inside the cylinder of the engine.

Nitrogen, phosphorus, and sulfur are also needed in relatively large quantities.

The Congo River has the second largest flow rate in the world after the Amazon, which has no falls or rapids (except near its sources).

Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen.

Like other beans, it hosts bacteria that fix nitrogen in the soil.

Furthermore, the situation in the Gulf of Mexico is worsening. Oil is not leaking at the rate of 1,000 barrels per day, as BP originally estimated, nor up to 19,000 bpd, as calculated by the Flow Rate Technical Group.

The amount of nitrogen and sulfur circulating through the Earth system has doubled.

Biological nitrogen fixation (BNF) could help to improve soil fertility and crop productivity.

Bioethanol has been shown to reduce nitrogen oxide emissions by 50 per cent

When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.

Now the one thing that I forgot to mention, is that to obviate the problem of the nitrogen narcosis all of those blue dots in our body you remove the nitrogen and you replace it with helium.

This design lowers the emissions of both nitrogen oxides (NO x ) and carbon dioxide (CO2).

Auroras and the atmosphere Auroras result from emissions of photons in the Earth's upper atmosphere, above , from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state.

And today, we are in a situation where we estimate that we've transgressed three boundaries, the rate of biodiversity loss, which is the sixth extinction period in the history of humanity one of them being the extinctions of the dinosaurs nitrogen and climate change.

(2006), when treating wastewater from metal refinery process (1.0 1.5 g NH4 N L and up to 22 g L of sodium sulphate), removed a nitrogen loading rate of 1.0 kg N m3 d with an efficiency of 95 in a system containing autotrophic granules.

In the '60s already, through the green revolution and the Haber Bosch process of fixing nitrogen from the atmosphere you know, human's today take out more nitrogen from the atmosphere than the whole biosphere does naturally as a whole.

And if we see the nitrogen dioxide and oxygen, I think we have the perfect E.T.

He observed that mixtures of alkali metal oxides and carbon react at high temperatures with nitrogen.
