Water flows through a 180 reducing bend, and the bend is in the vertical plane. The discharge rate is 0.25 mls, and the pressure at the centre of inlet section is 150 kPa gauge. If the bend volume is 0.1 m', it is assumed that the Bernoulli's equation is vaid, calculate the reaction force acting on the water by the bend to keep it in place. The metal bend weighs 500 N.
