The diameter of a pipe bend 30 cm at inlet and 15 cm at outlet and flow is turned through 120 (angle measured in clockwise direction between direction of fluid flow at inlet and outlet) in a vertical plane. The axis at inlet is horizontal and the centre of the outlet section is 1.5 m below the centre of inlet section. Total volume of water in the bend is 0.9 m. Neglecting friction, calculate the magnitude and direction of force exerted on the bend by water flowing through it at 250 lit/s and v I when inlet pressure is 0.15 N/mm.
