Density data are reported on 16 saturated hydrocarbon vapors at pressuresranging from 1000 to 8220 lb. per sq. in. and at temperatures ranging from 35?to 250?F. These data have been used to extend the compressibility-factor chartfor natural gases up to 10,000 lb. per sq. in.

On the Natural Density of the Niven Numbers
The College Mathematics Journal, 1984Some examples of Niven numbers are 8, 12, 180, and 4050. The set of Niven numbers is infinite since any positive integral power of 10 is a Niven number. Even though a variety of ideas, results and open questions were considered in [1], [2] and in papers presented at various mathematics meetings, the natural density of the set of Niven numbers has been ...

Density of a Single-Crystal Natural Silicon Sphere
IEEE Transactions on Instrumentation and Measurement, 2009The density of a single-crystal natural silicon sphere identified as ldquoAvo#3rdquo has been redetermined at the National Measurement Institute, Australia (NMIA), as part of an international collaboration to determine the value of the Avogadro constant.

Density of Liquefied Natural Gas
Journal of Petroleum Technology, 1969An experimentally derived tabular correlation for LNG density as a function of temperature, pressure, and gas gravity has been designed for use in the field. The advantages of this correlation are that a gas gravity analysis is more easily obtained than a composition analysis and that density is determined by direct interpolation of the gas gravity ...

Natural Gas Density Measurement with an Oscillator type Density meter
NCSL International Workshop & Symposium Conference Proceedings 2020, 2020The density results of a natural gas sample are presented, which were obtained by making the measurement experimentally using an oscillatory type density meter. This instrument is used in applications for research and development of measurement systems, as well as in industries.

Nature Inspired Node Density Estimation for Molecular NanoNetworks
Proceedings of the 3rd ACM International Conference on Nanoscale Computing and Communication, 2016Abstract The problem of estimating the node density in ad hoc networks is a significant one for protocol design. In molecular nanonetworks, the node density estimation problem poses additional challenges due to the limited processing and communication capabilities of the network nodes which necessitate the design of simple to implement distributed ...

Density‐Dependent Natural Selection
Ecology, 1971Density—dependent selective values illustrate the evolutionary effect of population—regulating processes that diminish an individual's probability of survival with increased crowding. The selective values, assumed to decrease as a linear function of density, lead in a mild environment to the evolution of phenotypes having a high carrying capacity, K ...
