Write a program for Problem 3.163, where the initial state, the volume ratio, and the polytropic exponent are input variables. To simplify the formulation, use constant specific heat.
Problem 3.163
A piston/cylinder assembly in a car contains 0.2 L of air at 90 kPa and 20?C, as shown in Fig. P3.163. The air is compressed in a quasi-equilibrium polytropic process with polytropic exponent n = 1.25 to a final volume six times smaller. Determine the final pressure and temperature, and the heat transfer for the process.
If cable AD is tightened by a turnbuckle and develops a tension of 1700lb , determine the force developed along the antenna tower AE at point A.
A kitchen contains a standard refrigerator and a window air conditioner. The refrigerator operates at steady state using 200 W of electric power and a COP of 3. If the kitchen is well insulated:
A steel rod of radius 0.01 m and length 2. M is pulled on with a tensile force of 200,000 N, and the bar stretches to a length of 2.08 m. The radius of the bar is reduced to 0.0099 m. Determine the stress, strain, Young's modulus (E), and Poisson's r..
