Repeat Problem 8.39 for a turbine efficiency of 85%. An ideal regenerative Rankine power cycle is shown
Question:
An ideal regenerative Rankine power cycle is shown in Fig. 8.38. Steam leaves the boiler at 15 MPa and 600°C with a mass flow rate of 10 kg/s. Steam is removed from the turbine at 1.6 MPa and directed to a closed feedwater heater. The remaining steam leaves the turbine at 10 kPa. Sketch the cycle on a T-s diagram and calculate:
i) The heat flow rate into the steam generator
ii) The mass flow rate diverted to the feedwater heater
iii) The net power output of the turbine
iv) The cycle efficiency

I am a retired teacher with 6 years of experience teaching various science subjects to high school students and undergraduate students. This background enables me to be able to help tutor students who are struggling with the science of business component of their education. Teaching difficult subjects has definitely taught me patience. There is no greater joy for me than to patiently guide a student to the correct answer. When a student has that "aha!" moment, all my efforts are worth it.
The Common Core standards are a useful yardstick for measuring how well students are doing. My students consistently met or exceeded the Common Core standards for science. I believe in working with each student's individual learning styles to help them understand the material. If students were struggling with a concept, I would figure out a different way to teach or apply that concept. I was voted Teacher of the Year six times in my career. I also won an award for Innovative Teaching Style at the 2011 National Teaching Conference.
