As a consulting engineering firm, a large corporation has hired your company to assess the environmental impact of a new industrial plant near the River Spray area (Next to NW University) and Vaal River. You discover that the proposed plant significantly impacts the surrounding communities and the river, which serves as a water source for several nearby communities and animals. However, the corporation refuses to accept your assessment report and refuses to engage the surrounding communities regarding the project. It requests you to alter or change specific outcomes of the report with the view that it will benefit their plan to build the plants, and this has caused a serious conflict with your consulting firm. The company proposed R1 million offer to you just to alter the report in their favour. a. Create presentation slides summarising your professional report on the Ethical and legal implications of the environmental assessment report of this plant. Your slides must include the following: Introduction, Findings (at least 5 of them and explain their impact on environment and health), Legal consequences of altering the report (e.g identify at least 3 and their implications on your consulting firm), Legal implications (use Water Act of 1998 for justification of your answers), Conclusions and Recommendations (Detail your conclusion/s. Presentations will either be on campus or online, and the date will be communicated accordingly. (25) USE PLAGIARISM CHECKER OR TURNITIN (PENALTIES FOR ANY PLAGIARIZED WORK WITHOUT PROPER REFERENCING) 2.2 2.3 2.4 2.5 2.6 2.7 Is R1 million enough, or what amount will be enough for you and why (3) Create a hazop study using chemicals and fumes that might result from this plant if it succeeds. (10) Evaluate five consequences or implications of not consulting nearby communities when planning for this plant. (10) Do you think the community must be engaged in this project? What are the four common responses or actions the community can take against this company, and why should this be the case? (9) How will you use Environmental Impact Assessment (EIA) Regulations " as a consulting firm before this project is approved? (justify using four answers). (8) Evaluate at least four environmental and economic implications and risks associated with improper disposal of hazardous chemicals. (12)

Consider a continuous-time system whose input $x(t)$ is related to its output $y(t)$ through the relationship $0.5 \frac{d}{dt}x(t) + 2x(t) = 2 \frac{d^2}{dt}y(t) + 0.5y(t)$ draw the block diagram of an implementation (realization) of this system using integrators, multipliers and adders. (Your realizations must not use differentiators.)

4. Pore Diffusion / Catalytic Reactor Design: The FIRST-ORDER gas-phase reaction A ? B is being conducted in a PBR on POROUS catalyst spheres of radius 1.2 cm. The intrinsic rate constant $k_v$ is 0.1 $s^{-1}$ and the diffusion coefficient $D_A$ is 0.001 $cm^2/s$. (a) Suppose in designing the PBR, the design engineer neglected pore diffusion. The resulting calculation showed that 10 kg of catalyst was needed to reach a conversion of 90%. As the newly hired design engineer, you are asked to redo the calculation correctly. How much more catalyst must you order to reach the same conversion? (b) Suppose you want to redesign the reactor such that it operates in a regime where the rate of pore diffusion is equal to the rate of surface reaction. You propose to do so by grinding the catalyst pellets down to a smaller size. To what diameter should you grind the catalyst? How much more catalyst should you order in this case?
