The  value  is  

Explanation:

From the question we are told that  

  The specific gravity of the first fluid  is  

  The  pressure of air is  

  The  atmospheric pressure is  

Generally the specific gravity of the second  fluid is mathematically represented as

Here   is the density of water with value

=>  

=>

pe = weightxheight = 2000x1000=2,000,000joules
