Find the cycle efficiency, Mechanical Engineering

Assignment Help:

Develop an EES Code for a Rankine cycle with reheat and with 2 open feedwater heaters.  The cycle is shown below:

Use the following conditions:
1.  700 psi, 850F
2.  500 psi
3.  750 F
4.  300 psi
5.  150 psi
6.  5 psi
7.  sat liq
8.  150 psi
9.  sat liq
10. 300 psi
11. sat liq
12. 700 psi

Assume all turbines are 80% efficient and all pumps are 90% efficient. Assume an mdot of 100 lbm/s through states 11, 12, 1, 2 and 3.  The mdots through the remaining components can be found from conservation of mass and energy to obtain the desired states. Assume a boundary temperature of 1500F from 12-1 and a boundary temperature of 77F from 6-7. Draw this cycle on a T-s diagram, labeling all temperatures and entropies on your x and y axis. Find the heat transfer, work, and entropy production for each component. Find the cycle efficiency. Print your EES solution to this single case
