In a small power plant, a steam at a rate of 2 kg/s and 4000 kPa enters a two stages steady-flow steam turbine. During the first stage, the steam expands in the turbine while doing work until the turbine exit pressure is 500 kPa. At that point, 10% of the steam is removed from the turbine for other uses. During the second stage, the remaining portion of steam, the 90% of the steam, continues to expand until it exits the...
