Water flows at a rate of 120 L/s in a 30 cm diameter horizontal pipe connected to a 20 cm diameter pipe through a vertical reducer bend. The change in water direction of the reducing bend is 120o. The vertical distance between the entrance and outlet of the bend is 1.5 m and the pressure at its entrance is 70KPa. The total weight of the bend material and water contained in it is 90 kg.
