The air at the inlet of the surpressor ('roots blower') is 20 °C at ambient pressure and compressed to 800 mbar and about 85 °C, we pump 6000 Nm³/h of air in the waste water basin which has a volume of 6800 m³. The starting temperature of the sewage water is 30 °C, it has about 0,5 to 1% of...
I'd like to calculate the amount of heat transferred from air when it is pumped into a (biological) waste water basin (8m depth).
I know the temperature, pressure and volumetric flow of the air. It is coarse bubble aeration, not very fine bubbles.
How do I start with this calculation?
