An open fwh receives steam at 150 psia 400 f from the

Question

1. Consider an ideal steam reheat cycle in which the steam enters the high-pressure turbine at 600 lbf/in.², 700 F and then expands to 150 lbf/in.². It is then reheated to 700 F and expands to 2.225 lbf/ in.² in the low-pressure turbine. Calculate the thermal efficiency of the cycle and the moisture content of the steam leaving the low-pressure turbine.

2. An open FWH receives steam at 150 psia, 400 F from the turbine and 1150 psia, 200 F water from the feed water line. Find the required fraction of the extraction flow in the turbine.
