A sugar mill in Florida has been disposing of bagasse by open-air burning. By using the dried bagasse as boiler fuel in the mill, you can generate 5000 kg/hr of surplus steam at 20 bar and 600 C. a) A new state of the art adiabatic and isentropic steam turbine is purchased, and the turbine exit pressure is 1 bar, what is the temperature of the exit steam, how much electrical energy (in KW) can be generated, and what fraction of the steam exiting the turbine is vapor? b) Another turbine is actually bought, which is adiabatic, but not isentropic. Same exit pressure of 1 bar produces 90% of the work produced by the turbine in part a. What is the termperature of the exit steam, what fraction of the steam exiting the turbine is vapor, and what is the rate of exntropy generation?
