Piston-cylinder with Steam is Cooled at Constant Pressure l Thermodynamics

Welcome to Engineering Hack! In today's video we are solving a problem on properties of pure substances. We have a piston-cylinder device that contains a steam that is being cooled at constant pressure until one-half of the mass condenses, and we want to find the Tv diagram of the system, the final temperature and the volume change. The problem requires you to know how to use the Temperature, Pressure and Superheated table, as that the specific volume can be calculated dividing the volume by mass, quality can be calculated dividing mass of the substance by total mass and some other pure substance properties as how to make a Tv diagrams. Everything else comes by analyzing the problem and the system at hand. This is problem 3.53. Problem statement: A piston-cylinder device contains 0.6 kg of steam at 200°C and 0.5 MPa. Steam is cooled at constant pressure until one-half of the mass condenses. (a) Show the process on a Tv diagram. (b) Find the final temperature. (c) Determine the volume change.

Well, you never should trust anything 100%. Make sure you are checking for yourself. When I’m solving the questions, I always solve on my own and then check the results against other sources. If there is divergence, I look for more sources. So while I can’t promise you everything will be 100% correct, I can promise I’ve done my due diligence before posting.
