TecJet 50 Flow Capacity
The following graphs are based on the density of the gas at 0.82 kg/m³.
Please use the following equations to modify the graphs to your requirements:
Using the example of landfill gas (60% CH
4
and 40% CO
2
)
Density = 1.221 kg/nm³
Gas temperature = 50 °C (max. = 65 °C)
Gas flow = 450 nm³/h
To correct the density and/or temperature:
Density = 1.221 * (273/(273+Tgas)) = 1.03 nm³/h
Flow = 450 * 1.221/1.03 = 532 nm³/h
Flow (at 0.82) = 532 * SQR(1.03/0.82) = 596 nm³/h
Maximum differential pressure (DP): 40 kPa
Minimum differential pressure: 3 kPa
Maximum absolute gas pressure (AP): 250 kPa
