Understanding Flow Rate Calculations
The IFLO-STG provides flow rate data under standard conditions, defined as a temperature of 20∘C and a pressure of 101.325kPa. To convert the flow rate from working conditions (Qn) to the flow rate in standard conditions (Qs), the following formula is used:
Qs=((0.101325+P)/0.101325)∗((273.15+20)/(273.15+t))∗Qn
Where:
- Qs: Flow rate in standard condition (Nm3/h)
- Qn: Flow rate in working condition (m3/h)
- t: Medium temperature in working condition (°C)
- p: Medium pressure in working condition (Gauge pressure, MPa)
A detailed flow range table for various gases like Nitrogen (N2), Oxygen (O2), Air, and Hydrogen (H2) across numerous nominal diameters is available in the product brochure.
