Question: A Rankin cycle is operating between 5 and 30 bar using water. The outlet to the boiler is 300C and the turbine efficiency is 90%.

A Rankin cycle is operating between 5 and 30 bar using water. The outlet to the boiler is 300C and the turbine efficiency is 90%. Find the Qh, Qc, turbine work output, pump work input, and the cycle efficiency, defined as: ?????? = ??? ???? ?? ????? ?? Include a table for the 4 streams (i.e. points on the diagram) that gives the estimates for pressure, temperature, entropy, enthalpy, and quality (i.e. % of vapor). Do not worry about the multiple points inside the boiler that are detailed in the Rankin cycle examples. Use all of the charts and tables at your disposal. Recognize that some of the axis, such as the pressure axis on the T-S diagram are logarithmic. This means that it is not as easy to "eyeball" a pressure that is in between the axis lines (for example, for fining a pressure between 1 bar and 10bar on the T-S curve). Use the P-H chart. H-S chart, and the steam tables provided to give you better estimates of the information you need
