Question

Please need clear and good hand writing

bled from bêtween the Task 3 - Rankine Cycle A simple steam power plant works as follows. Water is pumped into the boiler at point (1) on the diagram. Superheated steam leaves the boiler and goes to the turbine at point (2) The steam leaving the turbine is wet with dryness fraction x and goes to a steam condenser at (3). The condenser turns the steam into saturated water and this goes to a pump at (4) and the cycle is repeated. 6 The turbine has an Isentropic Efficiency of nis%. You should assume that the pump uses perfect compression. Given the set of conditions for each point in the circuit you must do the following: 8 1. Sketch the cycle on the Enthalpy - Entropy chart (T-s) attached. 2. Sketch the cycle on a Temperature - Entropy chart (h-s) attached. 3. Calculate the ideal and actual Dryness Fraction at point (3). 4. Calculate the ideal and actual Enthalpy at point (3). 5. Determine the Enthalpy at each point in the cycle. 6. Calculate the Heat Transfer rate into the boiler (Din) 7. Calculate the work Transfer rate from the turbine (Pout). 8. Calculate the Heat Transfer rate from the condenser (out). 9. Calculate the Thermal Efficiency of the plant. (nth) 10. Calculate and compare the Carnot Efficiency (ne) using the maximum and minimum cycle temperatures.
