To calculate the life cycle cost per unit for the power plant, we need to consider the cost of each item and the life period of each item.
Let's first calculate the cost of each item over their respective life period:
1. Heat energy collectors:
Cost = Rs. 35,000 per KW
Life period = 20 years
Cost over life period = Rs. 35,000 * 20 years = Rs. 700,000 per KW
2. Boiler+ steam turbine:
Cost = Rs. 14,900 per KW
Life period = 10 years
Cost over life period = Rs. 14,900 * 10 years = Rs. 149,000 per KW
3. Electric generator:
Cost = Rs. 6,500 per KW
Life period = 10 years
Cost over life period = Rs. 6,500 * 10 years = Rs. 65,000 per KW
4. Accessories, tools:
Cost = Rs. 3,000 per KW
Life period = 5 years
Cost over life period = Rs. 3,000 * 5 years = Rs. 15,000 per KW
Now, we need to calculate the total cost over the life period for the power plant. We sum up the costs of all the items:
Total cost over life period = Cost of heat energy collectors + Cost of boiler+ steam turbine + Cost of electric generator + Cost of accessories, tools
Total cost over life period = Rs. 700,000 per KW + Rs. 149,000 per KW + Rs. 65,000 per KW + Rs. 15,000 per KW
Next, we need to determine the life cycle power generation of the power plant. Let's assume it generates X units of power over the life period.
Now, we can calculate the life cycle cost per unit for the power plant:
Life cycle cost per unit = Total cost over life period / X
Please note that we need the value of X (power generation over life period) to complete the calculation.
