A heat exchanger has been designed for use in a chemical process. A standard type of heat exchanger with negligible scrap value costs 4000s and will have a useful life of 6 years. Another proposed heat exchanger of equivalent design capacity costs 6800s but will have a useful life of 10 years and a scrap value of 800S. Assuming an effective compound interest of 8% percent per year, determine which heat exchanger is cheaper by comparing the capitalized costs?
Problem 6: A heat exchanger is to be used in a heating process. A standard type of heat exchanger (code name HX1) has an installed cost of $20,000 and a useful life of 6 years. At the end of its useful life, the standard heat exchanger has a negligible salvage value, assumed to be 0. Another type of heat exchanger (Code name HX2) with equivalent design capacity is priced at S34,000 ihstalled, has a useful life of 10 years and...
A project has a service life of five years with the initial investment outlay of $200,000. If the discounted payback period occurs at the end of the project service life (say five years) at an interest rate of 10%, which of the following statements is true? A-The discounted payback period occurs at the end of project service life. B-The NPV of the project may equal or be greater than 0. C-We should invest in the project D-All of the above.
lets suppose, My initial investment is 5,00,000 Rs and I invest 1,00,000 rs per month . My investment earns 10 percent P. A. and after 3 year I increased my investment to 2,00,000 per month. and the intrest rate or return is same 10 percent per annum. After 6 years i startes to invest 3,00,000 rs per month and intrest rate or return is same. after 10 year i startes to invest 10,00,000 rs per month and intrest remains same....
A geothermal heat pump can save up to 85 % of the annual heating and cooling bills of a certain home in the northeastern U.S. In this region, the yearly cost of conventionally heating and cooling a 2,000 square foot house is about $2 comma 600 . With a federal tax credit of 30 % on the total installation of the system, how much can a homeowner afford to spend for a geothermal heat pump if the interest rate is...
5 It is estimated that a certain piece of equipment saves Rs.260000 PLO-2 6 per year in labour and material costs. The equipment has an njk expected life of 8 years and a market value of Rs.80000. If the company must earn a 15% annual return on such investment, how much is justified now for the purchase of this equipment. Draw a cash-flow diagram from the company's view point.
An investment has an initial cost of $300,000 and a life of four years. This investment will be depreciated by $60,000 a year and will generate the net income shown below. Should this project be accepted based on the average accounting rate of return (AAR) if the required rate is 29.5 percent? Why or why not? Net Income Year 1 $14,500 16,900 N 3 19,600 4 23,700 Select one: a. No, because the AAR is 29.5 percent b. Yes, because...
Fimbrez Corporation has provided the following data concerning an investment project that it is considering: initial investment.............. $360,000 Annual cash flow............. $118,000 per year Expected life of project..... 4 years Discount rate................... 12% The net present value of the project is closest to: $358,484 $360,000 $(1,516) $112,000
Ch.15_104_005. A $350,000 capital investment proposal has an estimated life of four years and no residual value. The estimated net cash flows are as follows: Year Net Cash Flow Year Net Cash Flow $150,000 $104,000 130,000 90,000 The minimum desired rate of return for net present value analysis is 12%. The present value of $1 at compound interest of 12% for 1, 2, 3, and 4 years is 0.893, 0.797, 0.712, and 0.636, respectively. Determine the net present value.

1. A machine costs $35,000 to buy and $5,000 per year to operate and maintain. It will have a salvage value of $8,000 in 9 years. It will generate $10,000 per year in net revenue for the first four years, and then the revenue will fall by $1,000 each year after. If the company purchasing the machine uses a MARR of 7% to make project, find the NPW, NEW, and AW....
