Unformatted text preview: 3 /lb. (c) Propane at p=1 MPa, T =85C, determine v, in m 3 /kg. 3.21 As shown in Fig. P3.21, a closed, rigid cylinder contains different volumes of saturated liquid water and saturated water vapor at a temperature of 150C. Determine the quality of the mixture, expressed as a percent. Fig. P3.21 3.22 As shown in Fig.P3.22, 0.1 kg of water is contained within a piston-cylinder assembly at 100C. The piston is free to move smoothly in the cylinder. The local atmospheric pressure and acceleration of gravity are 100 kPa and 9.81 m/s 2 , respectively. For the water, determine the pressure, in kPa, and volume, in cm 3 . Fig.P3.22 3.24 Water contained in a closed, rigid tank, initially saturated vapor at 200C, is cooled to 100C . Determine the initial and final pressures, each in bar. Locate the initial and final states on sketches of the p-v and T-v diagrams....
