The energy loss due to sudden enlargement.
Answer to Problem 10.1PP
The energy loss due to sudden enlargement in terms of head is
Explanation of Solution
Given information:
For pipe 1:
Outer Diameter D = 50 mm
Pipe wall thickness t1= 2.4 mm
Thus, Inner diameter of the pipe 1 = D − 2t = 45.2 mm
The velocity of flow v1= 3 m/s
For pipe 2:
Outer Diameter D = 90 mm
Pipe wall thickness t2= 2.8 mm
Thus, Inner diameter of the pipe 2 = D − 2t = 84.4 mm
Calculation:
The energy loss due to sudden enlargement is given in terms of head lost. The formula for head loss due to sudden expansion is given by:
Putting given values in equation (1)
Conclusion:
Thus, the energy loss due to sudden enlargement in terms of head is
