As can be seen in Table 5, the total Ampere-hour rate is 27.1 Ah. Divide by an ambient temperature factor of one for a 77°F room, and by a 0.8 battery-aging factor. Required total Ah rate = 27.1 Ah ÷ 0.8 = 33.9 Ah. dictionary class javaWebAdditionally, the ' duty cycle' is the amount of time a compressor is providing consistent pressure (PSI) and flow (CFM). So, if a compressor advertises a 100% duty cycle at 25 CFM and 125 PSI, it means that the compressor will provide 25 CFM and 125 PSI for 100% of the time with the help of a storage tank.
