Answer:
Input power of the geothermal power will be 686000 J
Explanation:
We have given density of brine 
Rate at which brine is pumped 
So mass of the pumped per second
Mass = volume × density = 
kg/sec
Acceleration due to gravity 
Depth h = 200 m
So work done 
Efficiency is given 
We have to fond the input power
So input power 
So input power of the geothermal power will be 686000 J
