(1) Water at 15 degrees celcius flows through a nozzle that contracts from a diameter of 10cm to 2cm. The exit speed is V2=25m/s, and atmospheric pressure prevails at the exit of the jet. Calculate the pressure at section 1 and the force required to hold the nozzle stationary. Neglect weight.
(2). This bend discharges water (1000 kg/m^3) into the atmosphere. Determine the force components at the flange required to hold the bend in place. The bend lies in a horizontal plane. Assume viscous forces are negligible. The interior volume of the bend is 0.25 m^3, D1=60cm, D2=30cm, and V2=10m/s. The mass of the bend material is 250kg.
