A: Power input is the power required in order to agitate the impeller. Large impeller requires higher power input and it increases the cost of operation. Impeller tip speed is the speed of impeller at the tip, which related to the shear stress condition. Higher impeller speed, higher impeller tip speed.]]> 2017-03-27 02:49:44 UTC https://padlet.com/farizanmohd/BTC3303Topic5/wish/162686803 Some questions can be asked from this topic; farizanmohd https://padlet.com/farizanmohd/BTC3303Topic5/wish/162687259 1. What are the steps/transport phenonomena involved for oxygen transfer in submerged fermentation?
2. Explain briefly about the influence of agitation speed on the oxygen transfer.
3. Why the KLa measurement and it's value is important in the cultivation of microorganisms?
4. Explain the effect of microbial growth if the agitation speed is increased to a maximum value.
5. Explain briefly the effect of bubble size on the oxygen transfer.
6. How the addition of antifoam influence the performance of aerobic microbial cultivation process?
