Determine the phase or Phases in a system consisting of water at the following conditions and sketch p-v and t-v diagrams showing the locations of each state if a condenser process is internally reversible (i.e. )where the heat transfer q = -5 kj/kg occurs at constant temperature of 27 degree c, does the entropy for the process increase or decrease? Air (ideal gas) enters an insulated compressor operating at steady state at 1 bar 327 degree c and exits at 5 bar, 447 degree c. neglecting ke and pe changes determine or in other words determine whether the process is internally reversible, irreversible, or impossible? Explain the difference in operations of carnot cycle and rankine cycle using any p-v or t-v diagram (must draw the diagrams for both cycles) at steady state, a new power cycle is claimed by its inventor to develop 6 kw for a heat addition rate of 7 kw if the cycle operates between reservoirs at 1000 and 250 k, evaluate this claim a power plant schematic is shown in the figure The turbine and pump processes are irreversible. The heat transfer from turbine is 50 kJ and the pump is adiabatic. The turbine entering and exit velocities are 40 m/sec and 150 m/sec respectively. The constant pressure processes occur in the boiler and condenser. The state properties are listed below.Explanation / Answer
1 .. a.. saturated liquid b...liquid +vapour ... c... ice
2 as heat is transfered from vapur to surrounding entropy of process wil increase
3 imposible as gibs free energy free energy for this process is possitive
5 carnot efficiency =1-250/1000 =0.75
according to inventor efficiency =6/7 =0.85
hence claim is false
