← ScienceWithin a geothermal power plant, which mechanism limits energy extraction due the presence of non-condensable gases?
A)Partial pressure vapor-liquid equilibrium✓
B)Increased fluid kinematic viscosity
C)Turbine blade fatigue crack propagation
D)Reduced scaling chemical reaction kinetics
💡 Explanation
The presence of non-condensable gases increases partial pressure of the vapor, impairing phase transition in the condenser; vapor-liquid equilibrium drives condensation because it is more favorable than the alternatives across temperature gradient; rather than kinetic concerns
