Читать книгу Agitator Design for Gas-Liquid Fermenters and Bioreactors - Gregory T. Benz - Страница 19

From the above combinations of agitator power and airflow, calculate the agitator brake power, which is the shaft power divided by the mechanical efficiency of the agitator, which includes gear drive losses as well as seal losses. Calculate the compressor brake power, including pressure losses through lines, filters, and sparger as well as compressor efficiency. Add the agitator and compressor brake power together and choose the combination with the lowest total, unless other constraints govern, such as CO₂ in the exhaust gas.
