PART III: STEAM TURBINE ANALYSIS Problem Statement hint) Using microsoft excel for solution 7. A simple steam turbine operates at low pressure of P4 = P4 = 100 kPa and high pressure of P2 = P2 = 3.5 MPa. Steam enters the condenser at saturated mixture with 90% vapor and 10% liquid (state 4) and exits at saturated liquid (state 1) Water then pumped where its enthalpy reaches 430 kJ/kg (state 2) The system boiler generates steam at 315 C (state 3) Assume the mass flow rate of water is 1 kg/s a. Create a new sheet. Name it Solution" b. Use Water Property Table you created and use first law of thermodynamics to evaluate steam turbine work net output and cycle efficiency. C. Your solution should be in a table showing all properties: state number, phase, all properties (no need for state 2, h is given) all processes work net output, efficiency P T h State Phase kPa m/kg m3/kg sat liquid liquid superheated sat mixture V 1 2 3 4 eff Wp kW QB kW WI kW Qc kW WNET kW d. Name the table "TABLE 1: Steam Turbine Performance" e. Draw the system in Figure 1 using straight lines with markers. Use the same sheet. f. Name the series "solution 1" g. Show legends Parametric Analysis for Steam Turbine Cycle 8. Determine system performance when turbine inlet temperature becomes 455 C (state 3) a. Repeat part 76 and 7c to evaluate all processes and system efficiency. Use the same sheet. b. Name the table TABLE 2: Steam Turbine T3" 9. Determine system performance when turbine inlet pressure becomes 4.5 MPa a. Repeat part 7b and 7c to evaluate all processes and system efficiency. Use the same sheet. b.
