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
Answer:
The minimum diameter is 1.344 in
Explanation:
The angular speed of the driveshaft is equal to:
Where
N = rotational speed of the driveshaft = 2900 rpm
The torque in the driveshaft is equal to:
Where
P = power transmitted by the driveshaft = 134 hp = 73700 lb*ft/s
The minimum diameter is equal to:
Where
T = shear stress = 6100 psi
τ = 242.68 lb*ft = 2912.16 lb*in
