Airodyne Wind, Inc. has wind tunnels that can op­erate vertically or horizontally for evaluating the effects of air flow on a component’s PCB response and reliability. The company expects to build a new tunnel that will be outfitted with multiple sen­sor ports. For the estimates below, calculate the equivalent annual cost of the project.


AW = -800,000(A/P,10%,4) – 300,000(P/F,10%,2)(A/P/10%,4) - 950,000
+ 250,000(A/F,10%,4)
= -800,000(0.31547) – 300,000(0.8264)(0.31547) - 950,000
+ 250,000(0.21547)
= $-1,226,720 per year
