← ScienceWhich limit worsens the power output when an urban district's geothermal plant exceeds groundwater recycling thresholds?
A)Higher turbine back pressure develops
B)Fluid temperature drops at inlet✓
C)Local faults trigger fluid release
D)Increased scaling blocks wellbore flow
💡 Explanation
Fluid temperature drops occur because exceeding threshold groundwater recycling reduces the heat available for phase change in the heat exchanger; therefore, lower temperature drive hinders turbine performance rather than the alternative back pressure increase with restricted flow.
