4. Reconsider the top-secret military power supply for artic environments that you worked in a previous homework (HW 7, Q2). Previously, you modeled it as a Carnot cycle; now you will use the more realistic Rankine cycle with R-22 as the working fluid. The boiler operates at 1000kPa with a maximum temperature of 30C. The condenser is isobaric and operates at 5C. a. Calculate the quality leaving the turbine and the specific enthalpy exiting the turbine (in kJ/kg ) [0.973&242.44kJ/kg ] b. Determine the specific-work produced by the Rankine cycle turbine (in kJ/kg ), assuming it is ideal (reversible) and adiabatic. [20.47 kJ/kg] c. Show the cycle on a T- (temperature vs. specific entropy) diagram relative to the 2-phase region and label the isobaric pathway of the boiler with its pressure (in kPa ). d. Determine the specific-work required by the Rankine cycle pump (in kJ/kg ), assuming it is ideal (reversible) and adiabatic. [0.444kJ/kg] e. Determine the specific- QH for the Rankine cycle (in kJ/kg ) [224.15kJ/kg] f. Calculation the Rankine cycle (thermal) efficiency [8.9\%] g. Compare the required material strength (using maximum cycle pressure) and cycle efficiency of this Rankine cycle with a Carnot cycle operating with the same TH(30C) and TL(5C) by calculating the percent change in max pressure and thermal efficiencies.
