Homework Assignment 8 1. Argon in the amount of 0.6 kg fills a 0.09- 3 m piston- cylinder device at 200 kPa. The piston is now moved by changing the weights until the volume is 4 times of its original size. During the process, argon’s temperature becomes double of its original temperature. Please determine the final pressure in the device. 2. Determine the specific volume of superheated water vapor at 10MPa and 400⁰C, using (a) the ideal gas equation (b) the generalized compressibility chart (c) the stream table (d) the error involved in case (a) and (b)
