PLO-3: Design/ Development of Solutions: An ability to design solutions for complex
engineering problems and design systems, components or processes that meet specified needs with
appropriate consideration for public requirements, and environmental considerations.
PLO-6 The Engineer and Society: An ability to apply reasoning informed by contextual
knowledge to assess societal, health, safety, legal and cultural issues and the consequent
responsibilities relevant to professional engineering practice and solution to complex engineering
problems.
PLO-7 Environment and Sustainability: An ability to understand the impact of professional
engineering solutions in societal and environmental contexts and demonstrate knowledge of and
need for sustainable development.
CLO 1: Design the conventional power plants operating under different configurations.
CLO 2: Understand responsibility to work closely with society for Power generation problems
identification
CLO 3: Analyze the environmental footprints of different power plants
Attribute 1: Preamble: Engineering problems which cannot be resolved without in-depth
engineering knowledge.
Attribute 2: Range of conflicting requirements: Involve wide-ranging or conflicting technical,
engineering and other issues.
Attribute 3: Depth of analysis required: Have no obvious solution and require abstract thinking,
originality in analysis to formulate suitable models.

i) Inlet pressure to the turbine varies from 4MPa to 10 MPa and the temperature varies from
350°C to 500°C.
ii) Exit from the final turbine is between 0.0075 MPa to 0.01 MPa
iii) It should have reheating.
iv) At least two to three feed heaters, a mix to open and closed feed heater is preferable.
v) You are free to choose reheating and feed heater pressures.
Do the following
(a) Design manually and on one of the following software
• MATLAB
• Engineering equation solver (EES)
(b) Find the mass flow rate of steam.
(c) Calculate the thermal efficiency of steam.
(d) Calculate turbine and pump work.
(e) Find back work ratio.
(f) Amount of water required for the cooling purpose.
(g) Optimize the power and cost per unit using the changeable variables.
(h) Find the cost per unit by using Ther-coal, LNG and furnace oil.
(i) Describe basic components used in power plants like boiler, turbine, pumps, condenser,
cooling towers, feed-heater types and functions.
(j) What are the exhaust gases from the burning of coal, LNG and Furnace oil? Also comment
how these gases effect the environment and how this impact can be reduced.
(k) Draw block diagrams and T-s diagram (only T-s) with the help of EES® or MATLAB.
Assessment Criteria:
The assessment of the CEP will be carried out according to the assessment rubrics. The distribution
of the marks shows levels of the attributes achieved, that contribute towards the attainment of the
respective CLO, PLO and hence the cognitive domain level. In order to have an assessment at
individual level a CEP presentation will be taken from each group and the physical demonstration
of the model.
• 40 % of the marks will be allotted based on the report. These marks will be same for each
member who appears in viva. For any member not appearing in viva no marks will be
given.
• 30% of the marks for presentation and it is individual level.

• 30% of the marks for Simulink and Matlab model and simulation
• The distribution of marks in the CLO’s are:
CLO-1 = 30%
CLO-2 = 30 %
CLO-3 – 40%
• The maximum possible mark for the whole CEP is 100/ 100
• The selection criteria for the best, average and worst of the CEP amongst the student groups,
is as follows:
❖ 0 – 50 Total Marks (Worst)
❖ 50 – 80 Total Marks (Average)
❖ 80 – 100 Total Marks (Best)
