Water is flowing at a rate of 250 lt/sec. through a pipe of 30 cm diameter. If the pipe is bent by 135°, find the magnitude and direction of resultant force on the bend. The pressure of water flowing in the pipe is 400 kPa.
  • a)
    F = 53.6 kN; θ = 22.5°
  • b)
    F = 22.5 kN; θ = 53.6°
  • c)
    F = 49.75 kN; θ = 22.5°
  • d)
    F = 20.6 kN; θ = 35.6°
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Water is flowing at a rate of 250 lt/sec. through a pipe of 30 cm dia...
The pipe is of uniform cross sectional area. Therefore, the flow velocities at section 1-1 and section 2-2 are the same.
The pressure intensity is also the same at the two sections.
P1 = P2 = 400 kPa = 400 × 103 N⁄m2
Based on forces on pipe bends Force along the x-axis (on the pipe): Fx = dynamic force + static force
Force along the y -axis (on the pipe):
Fy = dynamic force + static force
Magnitude of resultant force on the bend is
And the direction of resultant force with x-axis is
An equal and opposite force will be required to hold the duct in position.
Note: That any particle in a free liquid jet experiences gravitational forces only and thus it can be solved as a projectile.
