ETFL 60 = Elevated Temperature Flame Limit @ 60 Â°C. HOC = Heat Of Combustion. Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes R- or Refrigerant.. Thus, CFC-12 may also be written as R-12 or Refrigerant 12.An alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond.hemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
Energy stored in a capacitor. The energy stored in a capacitor is the same as the work needed to build up the charge on the plates. As the charge increases, the harder it is to add more. Potential energy is the charge multiplied by the potential, and as the charge builds up the potential does too.
Be able to compute how much energy is stored in an electrical storage device like a battery or a capacitor. 1  The voltage across the device is a measure of the energy-in joules-that a unit charge-one couloumb-will dissipate when it flows through the device.n other words, the power flowing into the battery is: P = - Vb Ir = - 12 * 0.5 = - 6w. 1  The power flowing into the battery is negative! 2  The power flowing out of the battery is positive! 3  And, it makes sense because we know the battery supplies power. 4  Batteries are often rated in ampere-hours (or milliampere-hours) and an ampere-hour is really a ...
