please solve.

In the flowsheet below you have a combination of a reheat cycle and a regenerative cycle. There are two feedwater preheaters. A is closed feedwater preheater, while B is an open feedwater preheater. All turbines and pumps are adiabatic. a) Fill in the missing pressures in the (P3,P5,P7,P9, and P12). b) Determine the quality of Stream 12. Turbines I and II are 85% efficient. Using information provided in the Table 1, calculate the work produced by Turbine II (in kJ/kg ). Provide the numbers used for interpolation (if used). For S tream 10, at the given T and P in Table 1 use calculations to verify the value of H10=881.0kJ/kg given in the Table 1 . Determine the stream 2/ stream 1 mass flow ratio using the energy balance around the feedwater preheater A. You may use values from Table 1
