1. A steam power plant that operates on a simple ideal Rankine cycle is considered (see the fig. below for details). Calculate the quality of the steam at the turbine exit and the thermal efficiency of the cycle. Make any realistic assumptions if necessary. Now, suppose, the efficiency needs to be increased to 45% and you are asked to suggest two viable ways to avail that. a) Which two methods will you suggest? b) As per your suggestions, which parameters need to be modified for both approaches? Show your calculations for the modifications. c) Draw the comparative T-S diagram for all of your approaches. d) Among the two methods, which one would be better in your opinion and why?
