Q4: In fig 4.1 Consider a reheat - docs.google.com/forms regenerative vapor power cycle with two feedwater heaters, a closed 21 - The enthalpy of point 10 is * feedwater heater at 20 bar and an A: 569.669 KJ/Kg open feedwater heater at 3 bar. Steam enters the first turbine at (80 B: 567.669 KJ/Kg bar), (480 °C) and expands to (7 bar ). The steam is reheated to (440 °C) C: 565.669 KJ/ Kg before entering the second turbine, it expands to the condenser pressure of (8 KPa). The net power output of the cycle is (80 MW). * 22- The entropy of point 10 is * A: 1.56716 KJ/Kg.k Suam B: 1.6716 KJ/Kg.k C: 1.7716 KJ/Kg.K Cundetnet CS ALPa Closed heater Open 23- The enthalpy of point 11 is * 20Ss T20°C 10 12 13 Pump 1 A: 872.357 KJ/Kg Pump 2 Trap B: 882.357 KJ/Kg Fig 4.1 A reheat - regenerative vapor power cycle C: 892.357 KJ/ Kg

I want to know how this problem can be done using mollier-chart  please let me know what I did wrong in the Attached mollier-chart picture so the solution didn't come out to be right. The problem A steam power plant, operating with one regenerative feed water heating at the initial steam conditions of P=35 bar, T=440°C, exhaust pressure at 0.04 bar. Steam is bled from the turbine for feed water heating at a pressure of 1.226 bar.Determine1-Specific heat consumption2- Thermal efficiency of the cycle3- Thermal efficiency of the cycle neglecting regeneration

The efficiency of a Carnot Cycle can be determined using only the hot and cool temperature True False

H.W. 4.1. Consider a regenerative cycle using steam as the working fluid . Steam leaves the boiler and enters the turbine at 4 MPa, 400 oC. After expansion to 400 kPa, some of the steam is extracted from the turbine for the purpose of heating the feedwater in an open feedwater heater. The pressure in the feedwater heater is 400 kPa and the water leaving it is saturated liquid at 400 kPa. The steam not extracted expands to 10 kPa. Determine the cycle efficiency. Answers: 37.5%
