How do you calculate the gas rate?

The gas rate calculation is based on the formula: 3600 seconds in one hour multiplied by the difference between the final and initial readings of gas in cubic meters, divided by the test time in seconds.

For instance, if the final reading is 0.053 cubic meters higher than the initial reading, and the test time is 120 seconds, the gas rate would be calculated as follows: 3600 multiplied by 0.053 divided by 120, which equals 1.59 cubic meters per hour.

The power output can be determined by multiplying the gas rate by the calorific value of the gas in kilowatts per cubic meter. Assuming a calorific value of 10.76 kW/m³, the power output would be calculated as: 3600 multiplied by 0.053 multiplied by 10.76 divided by 120, resulting in 17.11 kW.

In some cases, a gross to net conversion rate may be applied to the power output. This rate typically accounts for inefficiencies and losses in the system.

Using a gross to net conversion rate of 1.1, the net power output can be calculated by dividing the gross power output by 1.1. In this example, the net power output would be: 17.11 kW divided by 1.1, resulting in 15.41 kW.
