1- A steam turbine receives (600 kg/hr) of steam at (25 bar, 350 C°). At a certain stage of the turbine, steam at the rate of (150 kg/hr) is extracted at (3 bar, 200 C°). The remaining steam leaves the turbine at (0.2 bar, 0.92 dry). During the expansion process, there is heat transfer from the turbine to the surroundings at the rate of (10 kj/s). Determine the power produced by the turbine.

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

1- A steam turbine receives (600 kg/hr) of steam at (25 bar, 350 C°). At a certain stage of the
turbine, steam at the rate of (150 kg/hr) is extracted at (3 bar, 200 C°). The remaining steam
leaves the turbine at (0.2 bar, 0.92 dry). During the expansion process, there is heat transfer
from the turbine to the surroundings at the rate of (10 kj/s). Determine the power produced
by the turbine.

A power plant operates in an idealized Rankine cycle, using water as the working fluid (Figure 3). The steam at the exit of the boiler has a pressure of 6 MPa and temperature of 600 °C (point 1). The water at the exit of the condenser has a pressure of 15 kPa (point 3). The condenser employs a nearby river as the cooling source, which can be regarded to have a constant temperature of 25 °C. The mass flow rate of the steam is 80 kg/s. The hot reservoir has a temperature of 1400 K. Regard water as an incompressible liquid. During pumping, the density of water remains unchanged as Point 3 in Figure 3. Qin Boiler i wwwwww Pump Turbine Wp 3 Figure 3 W₁ Cooling water Condenser
