A plant is proposing to install a combined heat and power system to supply electrical power and process steam. Power is currently taken from a utility company and steam is generated using on-site boilers. The capital cost of the CHP plant is estimated to be $23 million. Combined heat and power is expected to give net savings of $10 million per year. The plant is expected to operate for 10 years after the completion of construction.
Calculate the cumulative net present value of the project, at a discount rate of 12%, using MACRS depreciation with a seven-year recovery term. Also, calculate the discounted cash flow rate of return.
Construction will take two years, and the capital will be paid in two equal increments, at the end of the first and second years. The savings (income) can be taken as paid at the end of each year. Production will start on the completion of construction.
determine which heat exchanger is cheaper by comparing the capitalized costs.

Think about how a growth factor would work to attract the cell to the surface and how these proteins could be anchored to the surface so that this functionality is not compromised.
You decide to take 2.00 mL of the solution and add an excess of a concentrated sodium chloride solution. You obtain a solid with a mass of 3.407 g. What was the concentration of the original lead(II) nitrate solution?
A process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional select..
The nutritional information on a cereal box shows that one serving of dry cereal has 90 calories (actually kilocalories). If one were to burn a serving of cereal, the amount of heat given off would be sufficient to raise the temperature of 1 kg of..
What would be the reduction in income-tax charges for the first year of operation if the sum-of-the-years-digits method were used for depreciation accounting instead of the straight-line method?
