Answer:
It will take 0.72*10^8 hours
Explanation:
Potential energy formula is:
[tex]P_{E}=m*g*h[/tex]
Where:
m=2.66*10^7 kg
g=9.8 m/s^2
h = 2000 m
[tex]P_{E}=2.66*10^7*9.8*2000=5.21*10^{11}[/tex]
Potential energy of the water vapor is 5.21*10^11 Joule
When it converted to watt/hour it becomes 1.45*10^8 Watt/hour.
When its divide by 2 because of 2 kW pump is going to be used. It will take 0.72*10^8 hours
