A boiler delivers steam at 10 MPa, 550?C to a two stage turbine, as shown in Fig. 9.19. After the first stage, 25% of the steam is extracted at 1.4 MPa for a process application and returned at 1 MPa, 90?C to the feed water line. The remainder of the steam continues through the low-pressure turbine stage, which exhausts to the condenser at 10 kPa. One pump brings the feed water to 1 MPa and a second pump brings it to 10 MPa. Assume all components are ideal. If the process application requires 5 MW of power, how much power can then be cogenerated by the turbine?
Total stress analysis is usually preferred for construction of embankments and for excavations, we use effective stress analysis, but why? Total stress is Undrained strength of the soil
A floating platform is supported at each corner by a hollow sealed cylinder 1 m in diameter, the platform itself weighs 25kN in air and each cylinder weighs 1.2kN per meter of length.
