CAPILLARY TUBE SIZING INSTRUCTIONS: Develop individually an Excel program that computes the length of a capillary tube with conditions prescribed by P13-2. The program must provide a printout containing a problem statement, design conditions, a summary of specifications, and other relevant design details. PROBLEM STATEMENT P13-2. A capillary tube is to be selected to throttle 0.011 kg/s of refrigerant 12 from a condensing pressure of 960 kPa and a temperature of 35°C to an evaporator operating at -20°C a) Using Figs. 13-7 and 13-8, select the bore and length of a capillary tube. b) If the evaporating temperature had been 5°C rather than -20°C, would the selection of part (a)be suitable? Discuss assumptions that have been made.

Express the solution of the given initial value problem as a sum of two oscillations. Primes denote derivatives with respect to time $t$. Graph the solution function $x(t)$ in such a way that you can identify and label its period. $x'' + 16x = 36 \cos 2t$, $x(0) = x'(0) = 0$ Express the solution of the given initial value problem as a sum of two oscillations. $x(t) = ?$ (Simplify your answer. Type an exact answer, using radicals as needed.) Graph the solution function $x(t)$. Choose the correct graph below. Identify the period. P = ? (Type an exact answer in terms of $\pi$.)
