SOLVED:Pressurized feedwater in a steam power plant is to be heated in an ideal open feedwater heater that operates at a pressure of 2 MPa with steam extracted from the turbine. If the enthalpy of the feedwater is 252  kJ / kg and the enthalpy of the extracted steam is 2810  kJ / kg, the mass fraction of steam extracted from the turbine is (a) 10 percent (b) 14 percent (c) 26 percent (d) 36 percent (e) 50 percent

In steam power plants, open feed water heaters are frequently utilized to heat the feed water by mixing it with steam bled off the turbine at some intermediate stage. Consider an open feedwater heater that operates at a pressure of 1000 kPa. Feedwater at 50^∘ C and 1000 kPa is to be heated with superheated steam at 200^∘ C and 1000 kPa. In an ideal feedwater heater, the mixture leaves the heater as saturated liquid at the feedwater pressure. Determine the ratio of the mass flow rates of the feed

A steam power plant operates on an ideal regenerative Rankine cycle with two open feedwater heaters. Steam enters the turbine at 8 MPa and 550^∘ C and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.6 and 0.2 MPa. Water leaves both feedwater heaters as a saturated liquid. The mass flow rate of steam through the boiler is 16 kg / s. Show the cycle on a T -s diagram, and determine (a) the net power output of the power plant and ( b ) the thermal efficiency of the cycl
