CalculationofflowrateEinft3/hour

Q= E

Q= Flow rateinft3/time

E= HighFlamePowersettinginBTU/hr

Hi= HeatingvalueinBTU/ft3

Thus,fornaturalgas:

Q=40,000 BTU/hr = 38.50ft3/hr = 0.64ft3/min.

Q= 0.64ft3/min.

Calculationofthenaturalgasneededin1hourbya7.7G(4burners)atfullpower:

Q=38.50 *4 = 154ft3/hr = 2.56ft3/min.
