Question

For the cycle of Problem, investigate the effects on cycle performance as the higher extraction pressure takes on other values. The operating conditions for the open feedwater heater are unchanged from those in earlier problem. Assume that condensate drains from the closed feedwater heater as saturated liquid at the higher extraction pressure. Also feedwater leaves the heater at $12\ \mathrm{MPa}$ and a temperature equal to the saturation temperature at the extraction pressure. Construct suitable plots and discuss.

Step 1

1 of 21Given data:

$p_1=12\mathrm{MPa}=120\mathrm{bar}$

$T_1=480\mathrm{^{\circ}C}$

$p_2=2\mathrm{MPa}=20\mathrm{bar}$

$p_3=0.3\mathrm{MPa}=3\mathrm{bar}$

$p_c=p_4=6\mathrm{kPa}=0.06\mathrm{bar}$
