R-469A is used in climate simulation test chambers for reaching temperatures as low as –70 °C. It is used as a substitute for R-23. The properties of R-469A with regards to cooling rate, thermal compensation, and air distribution are almost identical to those of R-23.
−0.88 g/cm 3, still consistent with a rocky composition, and a lower core mass fraction of 49 ± 7%. [4] For comparison, Earth's core comprises about 32.5% of its mass. The 2020 study also suggests that about 4% of the planet's mass is composed of water, suggesting it could be an ocean world estimated to have an average ocean depth of 779 ± ...
With a fuel fraction of nearly 85%, the GlobalFlyer could carry 5 times its weight in fuel.. In aerospace engineering, an aircraft's fuel fraction, fuel weight fraction, [1] or a spacecraft's propellant fraction, is the weight of the fuel or propellant divided by the gross take-off weight of the craft (including propellant): [2]
UAN is a solution of urea and ammonium nitrate in water used as a fertilizer.The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers.
