Question

If someone could help with these questions it would be huge for alot of kid's grades.

Thanks!

1. Steam is supplied, dry saturated at 40 bar to a turbine, and the condenser pressure is 0.035

bar. If the plant operates on the Rankine cycle, calculate, per kilogram of steam:

a. The work output neglecting the feed pump work (2.5pts)

b. The work required for the feed pump (2.5pts)

c. The heat transferred to the condenser cooling water, and the amount of cooling

water required through the condenser if that temperature rise of the water is

assumed to be 5.5 Kelvin. (2.5pts)

d. The Rankine cycle efficiency (2.5pts)

2. In a Rankine cycle with reheat, steam at 500oC expands in a high pressure turbine till it

reaches the saturated vapor state. The steam is then reheated at constant pressure to

400oC, followed by an expansion in a low pressure turbine to 40oC. It is required to limit

the moisture content in the steam to 15%. Find:

a. The steam inlet pressure for the high pressure turbine (2.5pts)

b. The reheat pressure (2.5pts)

c. The cycle efficiency (2.5pts)

d. The net specific work output (2.5pts)

     i. Assume ideal processes

Explanation / Answer

dude, I just asked the same question as yours, the guy answered above was wrong! He didn't even give you the proper answer. The first question is ask for the pressure, and he gave you the work done...

Hope this link will help you.
