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. Calculate the horizontal and vertical components of the force required to hold the bend in place.
3. A pump draws water from a 20 cm diam suction pipe and discharges through a 15 cm diam pipe in which the velocity is 3.60 m/s. The pressure is-34.465 kPa at A in the suction pipe.
