Explanation / Answer

3. Square root extractor compensates for the non linear characteristics of the differential pressure sensor . It does so by converting a non linear signal to a llinear signal using a controller.So answer is C controller

4. Ratio control in-line blending is the technique of blending two or more products together by either volume or mass. So answer is A ratio

5. Three-way valves are especially designed for mixing applications and hence answer C is correct
