initialism = an abbreviation pronounced wholly or partly using the names of its constituent letters, e.g., CD = compact disc, pronounced cee dee pseudo-blend = an abbreviation whose extra or omitted letters mean that it cannot stand as a true acronym, initialism, or portmanteau (a word formed by combining two or more words).
f o = (20.9 - %O 2)/%CO 2, Where %O 2 is the percent O 2 by volume, dry basis, %CO 2 is the percent CO 2 by volume, dry basis, and 20.9 is the percent O 2 by volume in ambient air. The Fuel factor can be corrected for the amount of CO, by adding the percent CO on a dry basis to the CO 2, and subtracting half of the percent CO from the O 2. [2]
The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period.
Energy is often defined as the ability to do work. Energy carrier An energy carrier is a substance or phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes (ISO 13600). Energy content Amount of energy for a given weight of fuel. see also energy density Energy security Energy security Energy ...
The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...
