The facilities of an existing chemical company must be increased if the company is to continue in operation. There are two alternatives. One of the alternatives is to expand the present plant. If this is done, the expansion would cost $130,000. Additional labor costs would be $150,000 per year, while additional costs for overhead, depreciation, taxes, and insurance would be $60,000 per year.
A second alternative requires construction and operation of new facilities at a location about 50 miles from the present plant. This alternative is attractive because cheaper labor is available at this location. The new facilities would cost $200,000. Labor costs would be $120,000 per year. Overhead costs would be $70,000 per year. Annual insurance and taxes would amount to 2 percent of the initial cost. All other costs except depreciation would be the same at each location. If the minimum return on any acceptable investment is 9 percent, determine the minimum service life allowable for the facilities at the distant location for this alternative to meet the required incremental return. The salvage value should be assumed to be zero, and straight-line depreciation accounting may be used.
Develop project plans for the design and construction of the following processes. Use Figure 1.2 as a guide to the activities that must occur. Estimate the overall time required from launching the project to the start of operation.
find the voltage and power at the sending end and the voltage regulation.
Calculate the ratio of the network over the amount of heat absorbed at the high temperature of the cycle. How does this value compare to the theoretical efficiency of the Carnot cycle that is calculated based on the two operating temperatures?
consider the binary cycle using the sodium and steamwater in the sketch below and operating at conditions in table 1.
She wishes to calculate a project's PW with estimated costs of $35,000 now and $7000 per year for 5 years beginning 1 year from now with increases of 10 % per year thereafter for the next 8 years. Use a real interest rate of 12% per year to make t..
1. How many kilograms of methane (CH4) are in perfectly insulated piston with the following properties: Volume = 2 cubic meters. Pressure = 3 bar absolute. Temperature = 50 Celcius? The ideal gas law constant R = 0.00008314 cubic meters.bar/K/gmol. A..
Let the property P;.. in Eq 5.2-1 be the scalar 1 so that the integral in that equation represents the instantaneous volume V. Show that in this case
Develop a process schematic. Assume that this process is continuous. Show each product stream illustrating the impurity level with respect to the feed entering the particular separator.
