Concept Introduction:

The method of increasing the strength of a material by altering their average crystalline size is known as grain-size strengthening.

Expert Solution & Answer

Explanation of Solution

In a material, its grain boundary is considered invincible for the dislocations. These dislocations affect the stress buildup in the adjacent grain in the material and activate the dislocation sources and enable the deformation in the neighboring grain.

Changing the size of the grain by different means changes the number of dislocations which are there in that grain boundary.Thus, it increases the strength of the material.

At high temperatures, a small portion of this material with dislocated grain is subjected to solidification which generates crystal seeds and the rest of the material use this seed as template when they begin to solidify.

3) A pilot-plant Podbielniak centrifugal extractor operating at 11,400 x g (this is G₁) is capable of processing 500 mL/min of filtered fermentation broth and 125 mL/min organic solvent, giving a recovery of 95%. The rotating cylinder inside the extractor has a diameter of 20 cm and is 2.5 cm wide. You need to scale up this extraction by using a larger Podbielniak extractor that has a diameter of 91 cm and width of 91 cm and delivers 2,300 x g (G2). What flow rates (in L/min) should be used in the larger extractor to achieve the same recovery efficiency?
