**Rankine Cycle with Reheat and Regeneration** The diagram illustrates a Rankine cycle featuring both reheat and regeneration processes. This cycle is often used in thermal power plants to improve overall efficiency. The outlined process includes several key components: a boiler, a reheater, a high-pressure turbine, a low-pressure turbine, an open feedwater heater, and two pumps (high-pressure and low-pressure). **States of the Water Through the Cycle:** 1. **Condenser (State 1 to 2):** - **Pressure (P1 = P8):** 15 kPa - **Quality (x1):** 0.0 - Water is at a saturated state, ready for pumping. 2. **Pump (State 2 to 3):** - **Pressure (P2 = P3 = P6):** 350 kPa - Water is pressurized by the pump and sent towards the open feedwater heater. 3. **Open Feedwater Heater (State 3):** - Water mixes with steam extracted from the turbines. 4. **High-Pressure Pump (State 3 to 4):** - Water is further pressurized to enter the boiler. 5. **Boiler (State 4 to 5):** - **Pressure (P4):** 3.0 MPa - Water is heated to a high temperature, becoming superheated steam. 6. **High-Pressure Turbine (State 5 to 6):** - **Pressure (P5):** 2.9 MPa - **Temperature (Ts):** 600°C - Steam expands, performing work, and is then reheated. 7. **Reheater (State 6 to 7):** - Steam is reheated to improve efficiency before entering the low-pressure turbine. 8. **Low-Pressure Turbine (State 7 to 8):** - Steam expands further, performing more work, then it is condensed back to water. **Efficiency and Performance Information:** - **Adiabatic efficiency of pumps:** 80% - **Adiabatic efficiency of turbines:** 85% **Tasks:** - Sketch the cycle on a T-s (Temperature-Entropy) diagram. - Determine the following: a. Work output per kilogram for the turbines. b. Work input per kilogram for the pumps

Expert Solution
Step 1

Given that 

P1 = P 8 =15 KPa

 P5 = 2.9 MPa              T5 = 600°C

P4 = 3.0 MPa 

P2 = P3, = P6 = P7, = 350 kPa , T7= 500°C
