A practical power cycle produces steam from the boiler at 600 kPa and 425°C. The turbine has an efficiency of 90%. The condenser pressure is 100 kPa, and the pump operates ideally (i.e., isentropically). Determine the following: (a)      the work output from the turbine per kg of steam.(b)      the thermal efficiency of the cycle.(c)      the maximum possible efficiency of the cycle.There are three answers: (a), (b), and (c).   Other values must be taken from Perry's handbook. I am sorry if this will take a lot of your time. But I will upvote as a appreciation for your effort
