Sentences with phrase «unit mass»

I should qualify the statement in the first sentence above; my calculations indicate that it is true in South Australia and in terms of the amount of energy per unit mass of fuel.

This is the reason for which VO2max is generally measured on a per unit mass basis, it reduces the obvious disparities that will be observed in people of differing total body mass.

You vary («calibrate») conductivity and potential change per unit mass change in each cell until your model can reproduce the observed values over a given historical period.

As non-fusing helium ash accumulates in the core of a main sequence star, the reduction in the abundance of hydrogen per unit mass results in a gradual lowering of the fusion rate within that mass.

The range of uncertainty in the radiative forcings can be isolated from the uncertainties in the simulated sulphate loadings by considering the range in the normalised radiative forcing i.e., the radiative forcing per unit mass of sulphate aerosol (e.g., Nemesure et al., 1995; Pilinis et al., 1995).

Since muscle consumes more oxygen than fat, a more muscular person would be expected to have a larger VO2max, all else being equal, even when it is measured on a per unit mass basis.

He now wants to totally ignore that and treat the masses as constant across the flasks while using the heat capacity per unit mass of the gases.

And we started off initially thinking that hydrogen would make sense, but we came to the conclusion that the best way to optimize the cost - per - unit mass to Mars and back is to use an all - methane system, technically a deep - cryo methalox.

Xia believes the specific energy (the energy per unit mass) of the battery is still low compared with commercialized lithium - ion batteries, and the assembly process needs to be further optimized.

The dichotomy concerns the so - called angular momentum (per unit mass), that in physics is a measure of size and rotation velocity.

As the energy output of the helium fusion process per unit mass is only about a tenth the energy output of the hydrogen process, this stage will only last for about 10 percent of a star's total active lifetime.

A new study, published in Nature Communications, explore — through genetically engineered tobacco plants — whether it is possible to develop crops that require less water per unit mass of production.

EbNPs deliver up to 20 time higher efficiencies per unit mass of active ingredient.

In general, smaller materials and ones with rougher or more convoluted surfaces have a greater exterior surface area — per unit mass — than larger items or ones with smoother exteriors.

I think they have low temperature and thyroid (and sex) hormones, but their metabolic rate per unit mass is high, and I recall from one study their heat production per cell being high?

Basically the issues are that I - 129 has a relatively «soft» beta decay (75 kev), a relative short biological half - life in the body, and an extremely low specific activity (that is, number of decay events per second per unit mass).

It has great energy per unit mass (which is why space rockets use it, particularly in the upper states), but its energy per unit volume is very poor (not to mention it has to be cooled to -253 °C to be liquified).

Specific enthalpy at 0oC (hf) = 0 kJ / kg (from steam tables)(Specific - per unit mass) Specific enthalpy of water at 100oC (hf) = 419 kJ / kg (from steam tables)

and the heat content per unit mass is not necessarily proportional to the temperature.

1) If the atmosphere were isothermal, then a unit mass of atmosphere would have greater total energy (thermal + potential) the higher it is located and the further it is away from the surface heating source.

The amount of heat required to raise a unit mass of a substance by a unit of temperature.

The index is defined as the cumulative radiative forcing between the present add some chosen time horizon caused by a unit mass of gas emitted now, expressed relative to that for some reference gas (here CO2 is used).

Global Warming Potential (GWP)- An index, based upon radiative properties of well - mixed heat - trapping gases (greenhouse gases), measuring the radiative forcing of a unit mass of a given well - mixed greenhouse gas in the present - day atmosphere integrated over a chosen time horizon, relative to that of carbon dioxide.

The GWP takes into account the fact that many gases are more effective at warming Earth than CO2, per unit mass.

Values are the ratio of global warming from one unit mass of a gas to that of one unit mass of carbon dioxide over 100 years.

Finally, if a parcel entrains some dry environmental air as it rises, it has less latent heat to release per unit mass, and its temperatures will fall faster with height than the temperature profile generated by an undilute parcel.
