Once two of the three reduced properties are found, the compressibility chart can be used. In a compressibility chart, reduced pressure is on the x-axis and Z is on the y-axis. When given the reduced pressure and temperature, find the given pressure on the x-axis. From there, move up on the chart until the given reduced temperature is found.
Compressibility is an important factor in aerodynamics. At low speeds, the compressibility of air is not significant in relation to aircraft design, but as the airflow nears and exceeds the speed of sound, a host of new aerodynamic effects become important in the design of

Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.
The oxygen transmission rate of a gas through the packaging is defined as the amount of oxygen permeating per unit of permeable area and unit of time in a packaging system considering standardized test conditions (23 °C and 1 atm partial pressure difference). It is an effective tool to estimate the barrier properties of a certain material. [53]
F ex O 2 is the fractional amount of oxygen present in the excurrent air stream (what the animal has consumed relative to baseline per unit time). For example, values for BMR of a 20 g mouse ( Mus musculus ) might be FR = 200 mL/min, and readings of fractional concentration of O 2 from an oxygen analyzer are F in O 2 = 0.2095, F ex O 2 = 0.2072.
A U.K. woman had her breast cancer detected through AI after a routine mammogram came back as normal. Experts Drs. Nicole Saphier and Harvey Castro discuss the power of AI in cancer care.
Oxygen equivalent compares the relative amount of oxygen available for respiration at a variable pressure to that available at SATP.As external respiration depends on the exchange of gases due to partial pressures across a semipermeable membrane and normally occurs at SATP, an oxygen equivalent may aid in recognizing and managing variable oxygen availability during procedures such as ...
