Could subsection iv and onwards be solved please?

Could subsection Vii and onwards be solved please?

Get the following values for each stage: Stage 3: P3, T3, S3, H3 Stage 4: P4, T4, S4, H4 Explain how to get values please.

7. Steam at 7.2 MPa, 600OC expands in a Rankine turbine to 0.45 MPa. For 180 kg/s of steam, determine the work, the thermal efficiency, and the steam rate (a) for the cycle, (b) for the turbine with the same specifications, the brake steam is 7.40 kg/kW-h and the driven electric generator has an efficiency of 91%. (c) Find eb, nb, WK, and quality or actual exhaust steam. Please answer letter c. Thanks
