In the two-pipe system, water flows continuously from the inner pipe and air from the outer pipe (steady-state). ˙The pressure change in both pipes is negligible. In addition, heat interaction with the environment, kinetic and potential energy changes are also neglected. In this system shown in Figure 1, the water flowing from the inlet number 1 is in the state of saturated vapor (gas). In this case, calculate the outlet temperature (T2) for the given system, using the ideal gas approximation for air. (it should be solved iteratively.) (Please solve it on paper and solve it line by line. When you type it, it becomes too complicated to understand. Also please explain your solution and don't write too close. Thank you for your effort)

3. A gas spring behaves like a piston-cylinder device. At a certain instant when the piston is at a distance of 0.2 m from the closed end of the cylinder, the gas density is uniform at 20 kg/m³ and the piston begins to move away from the closed end. Find the rate of change of gas density at this instant if gas velocity is proportional to distance from the closed end with a linear variation from zero at the end to 20 m/s of the piston. 0.2 m → 20 m/s Piston -
