3. A steam turbine operates adiabatically and produces 4000 kW. Steam is fed to the turbine at 21 bar and 480°C. The exhaust from turbine is saturated steam at 0.1 bar and it enters the condenser where it is condensed and cooled to 30°C. What is the steam rate for the turbine, and at what rate must cooling water be supplied to the condenser if the water enters at 15°C and is heated to 25°C.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
