This is an Isothermal Compression of Ammonia [not an ideal gas] Ammonia in a piston-cylinder device initially at 700kPa, 303K undergoes a reversible isothermal compression process until the volume is reduced to 25% of the initial volume. a) Draw the process T-s and p-v-diagrams, relative to saturation lines. b) What is the heat and work per unit mass?
A room is divided by a barrier into two sections. One side of the room (state 1) has a volume of 1000 ft^3 and is initially at 70F, 50 psi and the other side of the barrier (state 2) has 200 lbm of air and is initially at 300F, 14.696 psi. The divider is removed and the air mixes until it reaches equilibrium (state 3). Find the final temperature and pressure of the room. You can assume removing the divider has a negligible effect on the air.
