Final answer:
The maximum rated output capacity of hydrogen generating appliances for outdoor locations is determined by dividing the standard cubic feet per minute of hydrogen by 250.
Step-by-step explanation:
In outdoor locations, the maximum rated output capacity of hydrogen generating appliances should not exceed a certain value per square feet of floor area. According to the regulations, this value is given by dividing the standard cubic feet per minute (scfm) of hydrogen by 250. So, the formula would be:
Maximum rated output capacity = (scfm of hydrogen) / 250
For example, if the scfm of hydrogen is 100, then the maximum rated output capacity would be 100 / 250 = 0.4 scfm per square feet of floor area.
