A one-half cubic foot test dial on a meter makes one revolution every 22 seconds. Approximately how much heat is being generated?

To determine the heat generated based on the given data, we can use the relationship between gas flow and heat output. The one-half cubic foot test dial indicates the volume of gas used in a certain timeframe, which is key in calculating the heat output.

Since the meter completes one revolution every 22 seconds, this means that it registers a flow of one-half cubic foot of gas every 22 seconds. To find out how much gas is being used in an hour, you can perform the following calculation:

1. Calculate the number of revolutions in one hour (3600 seconds):

• 3600 seconds / 22 seconds per revolution = 163.64 revolutions per hour.

2. Calculate the total gas volume used in one hour:

• Each revolution equals one-half cubic foot, so:

• 163.64 revolutions x 0.5 cubic feet = 81.82 cubic feet of gas per hour.

The heating value of natural gas is approximately 1,000 BTU per cubic foot. Therefore, to find the total heat output, multiply the total volume of gas used by the heating value:

• 81.82 cubic feet/hour x 1,000 BTU/cubic foot =
