Note - Please be clear and thorough in your explanation. On the graphs, PLEASE show the position of states relative to the critical point, saturation lines and isotherms or isobars as appropriate along with the path for any processes. Also, could you explain what data table you used and why. Thanks!!
Two kilograms of water execute a Carnot power cycle. During the isothermal expansion, the water is heated until it is a saturated vapor from an initial state where the pressure is 40 bar and the quality is 15%. The vapor then expands adiabatically to a pressure of 1.5 bar while doing 491.5 kJ/kg of work. Sketch the cycle on the p-υ coordinates below.

One and one-half pounds of water within a piston-cylinder assembly execute a Carnot power cycle. During isothermal expansion, the water is heated at 500 degree F from saturated liquid to saturated vapor. The vapor then expands adiabatically to a temperature of 100 degree F and a quality of 70.38%. Sketch the cycle on p-v coordinates. Evaluate the heat transfer and work for each process, in Btu. Evaluate the thermal efficiency.

Need Help with Thermodynamics Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 239°C from a pressure of 5.6 bar to a pressure of 3.4 bar. Evaluate the work, in kJ/kg. ------------------------------------------------------------------------------------------------------------------------------------------------------------------- Water, initially saturated vapor at 10.7 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored.

Reffering to this picture, water contained in a piston-cylinder assmbly, initially at 1.5 bar and a quality of 20%, is heated at constant pressure until the pistonhits the stops. Heating then continues until the water is saturated vapor. Show the process of the water in series on a sketch of the T-v diagram. For the overallprocess of the water, evaluate the work and heat transfer, each in KJ/kg. Kinetic and potential effects are negligible.please.... :)

1. (15pts) A power plant was assumed to described by an ideal Rankine cycle without any irreversibility. The boiler produces saturated steam at a pressure of 120 bar (I). The steam expands adiabatically thru a turbine exiting as a saturated vapor/liquid mixture at pressure of 0. Ibar (2). The mixture passes thru a condenser (P=0.1 bar) until it is all saturated liquid (3). It is then pumped adiabatically to the boiler pressure of 120bar (4)...
