Interpretation Introduction

Interpretation:

Controlled, manipulated, and disturbance variables in the given figure are to be identified. Also, the effect of time length required on the waste concentration in the dialysis treatment is to be explained.

Concept introduction:

A control system is a system that regulates or monitors the behavior or working of other devices/systems using control loops. It can be used to control a single device or large industrial processes.

Controlled variables (CVs) are the process variables that can be controlled, and its desired value is known as the set point.

Manipulated variables (MVs) are the process variables that are adjusted by the controller to keep its value close to the set point.

Disturbance variables (DVs) are the process variable that affects the controlled variables, but they cannot be manipulated and are associated with any changes in the operating environment of the ongoing process.

The periodic array below denotes a hypothetical lattice in 2D. 1. Is this a Bravais lattice? Why or why not?  2. Draw 3 different versions of unit cells. Of those 3, make one a primitive unit cell. 3. There is a special type of primitive unit cell that is called a ’Wigner-Seitz’ cell (look it up on- line, or in text books). In words, describe how it is defined, and draw it for the lattice above.  4. Why would it be useful to draw the primitive unit cell of a lattice as a Wigner-Seitz cell, rather than another random choice? Hint : What geometric property of a lattice was described to be useful in guessing material properties
The schematic figure below shows a face-centered cubic (FCC) lattice with a lattice constant of a. Draw the lattice vectors of a primitive unit cell for the FCC lattice. Also write them in equation form and derive an expression for the reciprocal lattice vectors of an FCC lattice Using these sets of reciprocal lattice vectors, draw (or generate) the reciprocal lattice of FCC in re- ciprocal space. Show that this reciprocal lattice is equivalent to a body-centered cubic lattice with a lattice constant of 4pi/a
