A rigid tank initially contains 1.4-kg saturated liquid water at 200°C. At this state, 25 percent of the volume is occupied by water and the rest by air. Now heat is supplied to the water until the tank contains saturated vapor only. Determine: (a) the volume of the tank (10 pts.) (b) the final temperature and pressure (15 pts.) (c) the enthalpy change of the water (15 pts.) (d) show the process on a T-v diagram with respect to saturation lines (10 pts.) Maximum size for new files: 100MB

What is the new temperature (in K) of a closed gas system when it's volume is compressed from 5.6 L to 2.3 L and initial temperature was 455ﾟ K

ReadSpeaker webReader: Listen             In a reservoir, the pressure of a compressed gas must not be increased past 825 kPa.  The gauge indicated 388 kPa when the temperature is 24oC.  Determine the maximum temperature which can safely be attained in the reservoir

Determine the volume flow rate and the density of carbon dioxide at the inlet and the volume flow rate at the exit of the pipe using (a) the ideal-gas equation and (b) the generalized compressibility chart. Also, determine (c) the error involved in the first case.
