Complete the following exercises. In each case locate the state on sketches of the T-v and p-v diagrams.
(a) Four kg of water at 100°C fills a closed container having a volume of 1 m3. If the water at this state is a vapor, determine the pressure, in bar. If the water is a two-phase liquid-vapor mixture, determine the quality.
(b) Ammonia at a pressure of 40 lbf/in.2 has a specific internal energy of 308.75 Btu/lb. Determine the specific volume at the state, in ft3/lb.
