State numbers in the table correspond to the location numbers shown in the power plant's schematic. State 4s is achieved if the turbine operates isentropically. State 4a is achieved if the turbine's isentropic efficiency is 85 percent. You must show your calculation work below the table to receive the full credits. Credits will be given mainly based on your answers in the table Enthalpy State Pressure Temperature (°C) (kJ/kg) Specific volume Entropy (m³/kg) (kJ/kg-K) Phase (Write quality if the phase is saturated mixture) Saturated liquid 1 10 kPa 2 10 MPa Do not fill Do not fill Do not fill 3 10 MPa 500 4s 10 kPa 4a 10 kPa Do not fill Do not fill Do not fill Do not fill A b) (10 points) Please copy the table below on your paper and fill in the missing information. Continue to assume that the turbine's isentropic efficiency is 85 percent. For the equation column, you do not need to present the derivation process from the general version of the energy balance. You must show your calculation work (ie, how you use the equations to obtain the numeric answers) below the table to receive the full credits. Credits will be given mainly based on your answers in the table.
