MME 3334a Assignment #2 January 21, 2014 1 Water is the working fluid in an ideal Rankine cycle with reheat. Superheated vapor enters the turbine at 10 MPa, 480 o C, and the condenser pressure is 6 kPa. Steam expands through the first-stage turbine to 0.7 MPa and then is reheated to 480 o C, Determine for the cycle (a) the rate of heat addition, in kJ/kg, (b) the thermal efficiency, (c) the rate of heat transfer from the working fluid passing through the condenser to the cooling water, in kJ/kg. 2. For the cycle of Problem 1, reconsider the analysis assuming the pump and each turbine stage has an isentropic efficiency of 80%. Answer the same questions as in Problem 1. 3. Water is the working fluid in an ideal regenerative Rankine cycle with one open feedwater heater. Superheated vapor enters the first-stage turbine at 16 MPa, 560 o C, and the condenser pressure is 8 kPa. The mass flow rate of steam

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
