3. In my basement, the hot water that travels to the baseboard heaters is transported through bare copper pipes. The pipes have an inner diameter of 13.9 mm, and an outer diameter of 15.9 mm. Lowe's sells pipe insulation that has an internal diameter of $d_i = 15.9$ mm, and outer diameter of $d_o = 22.5$ mm, with $R' = 2.1$ F ft hr/BTU at a cost of $0.76/m. Assume that the water flowing through the pipes results in a convection coefficient of $h = 55 \text{ W/m}^2 \text{K}$, and free convection in the basement of my house has a convection coefficient of $h = 10 \text{ W/m}^2 \text{K}$. Neglect radiation. Should I insulate my pipes? Justify your answer by calculating how long it will take for me to make up my investment in heat savings by assuming that it costs me $0.05/kW hr to heat my water with wood during the winter.

II. Project Description The project considers different signal processing techniques to analyze signals in both time and frequency domains. The project is divided into three parts namely: Numerical signal simulations using MATLAB, Fourier series and Fourier transform analysis and simulations, and oral presentation. In the first part, students will be more familiar how to use a numerical tool (e.g. MATLAB) to simulate a time domain signal. In the second part, analysis and simulations for Fourier series and Fourier transform are conducted in both time and frequency domains. Last part of the project considers your skills in presenting your work and measures the teamwork performance. Part A In this part, a numerical analysis tool (e.g. MATLAB or Octave) will consider to help students to simulate different signals in time domain. The target of this part is to let student be more familiar with signal's parameters mapping to MATLAB. Consider the signal $x(t)$ that is an input to the system $h(t)$ given as $\begin{cases} 0 & t < 0\\ 1 & 0 \le t \le 2\\ 0 & t > 2 \end{cases}$ $h(t) = \begin{cases} 0 & t < 0\\ e^{-2t} & t \ge 0 \end{cases}$ The output of the system $y(t)$ is the convolution of $x(t)$ and $h(t)$ given as y(t) = x(t) * h(t) a. Given x(t) and h(t), explain two methods to find the output y(t). b. Explain how to define the time vector for x(t) and h(t) in MATLAB and justify your selection. c. Write a MATLAB code to plot x(t) and h(t) and show all details on the figure d. Write a MATLAB code to find the output y(t) without using any MATLAB built-in functions e. Write a MATLAB code to find the output y(t) using MATLAB built-in functions f. Plot the output signal y(t) obtained in part (d) and (e) in one figure and comment on the results
