Answer:
The  pressure at point 2 is 
Explanation:
From the question we are told that 
    The speed at point 1  is  
    The  gauge pressure at point 1  is  
     The density of water is  
Let the  height at point 1 be   then the height at point two will be
 then the height at point two will be 
       
Let the  diameter at point 1 be   then the diameter at point two will be
 then the diameter at point two will be 
       
 Now the continuity equation is mathematically represented as   
          
 Here  are the area at point 1 and 2
  are the area at point 1 and 2 
     Now given that the are is directly proportional to the square of the diameter [i.e  ]
]
    which can represent as 
              
=>         
where c is a constant 
   so      
=>          
=>        
Now from the continuity equation
          
 
=>      
 
=>      
 
        
Generally the Bernoulli equation is mathematically represented as 
        
 So  
           
  
=>    
substituting values
