Help me answer letter A.
An engineer was tasked with evaluating a heat and power generation unit for an aluminium smelting plant. The management intends to expand the production facilities to meet growing demand for aluminium. The plan involves increasing the energy intensive smelting line from the present single line to three lines by end of 2022. To support the expansion plan, the company plans to install a self-sufficient power generation unit. Details of the energy requirement and the proposed power generation unit is given the following Table. Item Power requirement per smelting processing line 0.6 MW Proposed power generation unit: Supplier • System Description Mitsubishi Heavy Industries Ltd Steam power plant (Carnot heat engines principles) 35% • Overall thermal efficiency Prepare a mini technical power evaluation report for the above project. Your report should include the following items and in the following order: a. Total power (W) and heat (Q) requirement.
