Actual reheat regenerative cycle

Table 4.4a shows the state properties of the actual reheat regenerative Rankine cycle.

A steam power plant is using an actual reheat regenerative Rankine cycle. Steam enters the high-pressure turbine at 10,800kPa and 773.15 K, and the condenser operates at 15 kPa. The steam is extracted from the turbine at 2000 kPa to heat the water in an open heater. The steam is extracted at 475 kPa for process heat. The water is a saturated liquid after leaving the water heater. The work output of the turbine is 95 MW. The turbine efficiency is 82%. The pumps operate isentropically. Determine the work loss at each unit if the surroundings are at 295 K. 

Table 4.4a shows the state properties of the actual reheat regenerative Rankine cycle. The fraction of steam extracted is estimated from the energy balance In terms of the mass fraction z = we have +(I —z) Z/, ...
