A plant generates excess steam at 22 bar and 480 C degree. It is planned to use this steam as the feed to a turbine to generate electricity. There are 4500 kg/hr of steam available, it is planned that the exit pressure of the steam will be 2 bar. (Hint: the Knovel steam tables are a useful resource.)
a/ Assuming that the turbine is well insulated, what is the maximum power ( in kW) that can be generated by the turbine?
b/ A real turbine operating under the same inlet conditions and outlet pressure has an efficiency of 80%. What is the amount of power ( in kW) generated by the turbine and the outlet temperature?
