42 m and the stirrer speed is 1The viscosity of the fermentation broth is 10 −2 Pa s and the density is 1000 kg m −3Estimate the mixing time under nonaerated conditions42 m 2 1000 kg m − 3 10 − 2 kg m − 1 s − 1 2.

The magnetic bar is small primarily capsule like barThe bar is then acts as a stirrer when placed inside the liquid solutionThe magnetic bar then rotates on its own center with the help of attraction and repulsion forces between the electromagnet in the generator and the magnetic barThe magnetic bar has a resistant coating to chemicals to.

The magnetic stirrer can be powered by any voltage source the fan is rated toHowever make sure your magnets are strong enough to couple together from the fan to the stir bar with the rated speedIf the speed is too high the stir bar will not spin correctlyI used a 9V battery at first but used this set of 3 AAA batteries I had lying around.

The magnetic stirrer can be used with or without the hot plate onTo turn off the magnetic stirrer rotate the knob counterclockwise until you hear a click and the white mark is pointing downRemove the stir bar with a metal utensilThe stir bar will stick to it so you can lift it out easily.

The magnetic stirrer is a stirrer made of highquality magnetic steel covered with PTFE which is heatresistant wearresistant and corrosionresistantThe mixing work is carried out in a sealable container which is ideal and convenient to useThe magnetic stirrer can be integrated with auxiliary heating device which greatly facilitates.

The major amount of power consumed by a magnetic stirrer is for heating as the heating elements consists of only pure resistance the operating power factor can be taken as one and hence the power.

This is especially true for substances whose viscosities can change over timeFor example lotions typically thicken as they cool while a magnetic stirrer would be suitable for such a sample when its still warm as it cools the increasing viscosity will be too much for the mag stirrer to handleSpeed as measured by rotationsper.

Under normal fermenter operating conditions increasing the stirrer speed and gas flow rate improves the value of k L aTypical data for k L a in Newtonian fluids of varying viscosity are shown in Figure 10The strong dependence of k L a on stirrer speed is evident from Figure 1010a in this system doubling the stirrer speed N i resulted in an average 4.
