where P is the electricity power output, η total represents the efficiency of the
energy power rate, ρ represents the density of energy (kg/m
3
), g represents the
acceleration caused by gravity (9.81 m/s
2
), and H represents the effective pressure
head (m) in order to determine the net electricity energy generation.
Results and Discussion
The results of the P-s diagram suggested that the feedwater pumping pressure is no
longer incompressible, and thus it is easy to capture the geothermal heat from Earth
Magna by installation of water force through “hydrothermal convection pipe” systems in houses and buildings to force the heated water to rise up to the surface elevation of houses and buildings (Fig. 4.4).
Here, the P-s diagram confirms that both turbines are adiabatic which is determined by the integrated power output results from both of the turbines as suggested
to be 10.6 MW if no steam is bled from the turbine (9.65 MW) to supply the required
energy demand for a house or building (Fig. 4.5).
Thereafter, the net heat energy is clarified, and the result suggests that the power
output is subsequently transferred by function of the feedwater pump velocity, and
its associated deaerator function of the water mass flow rate, respectively [34, 35].
