The flow rate in standard condition: The flow rate is in the condition of 20℃ temperature and 101.325kPa pressure.
The unit of flow rate is optional: Nm3/h, Nm3/min, L/h, L/min, t/h, t/min, kg/h or kg/min.
The reduction formula of flow rate in working condition and flow rate in standard condition:
Qs: The flow rate in the standard condition (Nm3/h).
Qn: The flow rate in working condition (m3/h).
t: The medium temperature in working condition (℃).
p: The medium pressure in working condition (Gauge pressure, kPa).
