Q.2. ( 25 points) :ideal Rankine cycle steam power plant shown in the figure is designed for specific operoting condistions. The high pressure in the cycle is set at 4800 kPa , while the low pressure is 10 kPa . To ensure efficient use of the steam and minimize energy loss in the form of liquid ahoplets, the turbine exhaust qualify must be at least 90%. The power output target for the turbine is 7.5 mw .
a) What is the required borter exit temperature?
b) What is total mass flow rate?
