Compressed air pipeline diameter
Thread Content
A fermentation tank with a volume of 60 cubic meters, a maximum aeration rate of 1.5 times, a loading factor of 0.7, a theoretical aeration rate of 3780 cubic meters per hour, and an inlet air pressure of 0.25 MPA. The customer believes that the DN150 pipes meet the requirements. I calculate that the pipe diameter should be at least DN200. Everyone, please help analyze it!
230 mm is required for 10 m/s, and 189 mm is required for 15 m/s. The actual required wind speed is likely to be much lower than the theoretical value
The flow rate for DN150 is relatively high; will it generate a lot of noise? The pressure drop is still acceptable, at 6–7 kPa per 100 meters
