56% 60. DeVault Services recently hired you as a consultant to help with its capital budgeting process. The company is considering a new project whose data are shown below. The equipment that would be used has a 3-year tax life, would be depreciated by the straight-line method over its 3-year life, and would have a zero salvage value. No new working capital would be required. Revenues and other operating costs are expected to be constant over the project's 3-year life. What is the project's NPV? Risk-adjusted cost of capital = 10.0% Net investment cost (depreciable basis) = $65,000 Straight-line deprec. Rate = 33.3333% Sales revenues, each year = $65,500 Operating costs (excl. deprec.), each year = $25,000 Tax rate = 35.0% a. $15,740 b. $16,569 c. $17,441 d. $18,359 e. $19,325

4) [25 pts] A feedback process is shown below. Suppose $G_d = \frac{K_d}{1 + \tau_d s}$, $G_p = \frac{K_p}{1 + 2\xi\tau_p s + \tau_p^2 s^2}$, $G_c = K_c$, $G_m = G_v = 1$. y_{sp} $G_c$ $G_v$ $G_p$ $G_m$ d $G_d$ +- + y a) Write expressions for the servo and regulator responses. b) Using the final value theorem, write an expression for the offset for the servo and regulator responses assuming unit step changes (assume the changes happen separately). c) Verify analytically that if we change from P to PI control the servo and regulator offsets become 0. d) If $K_p = 1$, $\xi = 0.5$, and $\tau_p = 2$, prove that the process is stable without using Simulink. e) Show that the overall loop (with PI control) is stable for $K_c = 10$, $\tau_I = 4$ and unstable if $K_c = 10$, $\tau_I = 1$.
