A double nozzle lying in a horizontal x-y plane discharges water into the atmosphere at a rate of 0.5 m3 /s. Assume the water speed in jets A (10 cm in diameter) and B (12 cm in diameter) are the same. The pipe is 30 cm in diameter. Find the force acting on the flange bolts required to hold the nozzle in place.

The force is  

Explanation:

The diagram for this question is shown on the first uploaded image  

At Equilibrium the summation of the of force on the vertical axis is zero

         i.e  

=>            

  is the is the speed of water at the nozzle which can be mathematically evaluated as

substituting   for R and for

  is the is the speed of water at the pipe which can be mathematically evaluated as

substituting   for R and for

is he density of water with value

Substituting values into the equation above

At Equilibrium the summation of the of force on the horizontal axis is zero

                  i.e  

=>            

               Since The speed at both A and B nozzle are the same then remains the same

 Substituting values

=>                        

   Hence the force acting on the flange bolts required to hold the nozzle in place is

46.25KN
