Fluid Mechanics Problem 6 The diameter of a pipe bend is 300 mm at inlet and 150 mm at outlet and the flow is turned through 60 o in a vertical plane. The axis at inlet is horizontal and the centre of the outlet section is 1.5 m above the centre of the inlet section. The total volume of fluid contained in the bend is 0.085 m 3 . Water is flowing through the bend at 0.2 m 3 /s when the inlet pressure is 140 kPa. Friction may be ignored. i) Use continuity to find the water velocities at the inlet and the outlet. ii) Use the Bernoulli equation to find the pressure at the outlet. iii) Calculate the components of the impact force on water. iv) Hence determine the magnitude and direction of the net force exerted on the bend.
