1. A smoothly contoured nozzle with outlet diameter d2 is coupled to a straight pipe by means of flanges. Water flows in the straight pipe of diameter d₁, and the nozzle discharges to the atmosphere. The pipe and nozzle are set in horizontal. Assume the fluid density p is constant. Under steady flow conditions, the force F is required to hold the nozzle in place. You may ignore any effects of viscosity. V1, P Om,in d₁ v2, P2 dz $m,out (a) Build the mass balance for the control volume. Use d₁ and d₂ to express the outlet velocity, v2 by v₁ from the mass balance. aff of botoxs bundley lets sdt not concied muitnement add blinds (b) Find the outlet mass flowrate, Om,in and Om,out (c) Build the energy balance for the control volume. Find the pressure difference, P₁ - P2 by using p, d₁, d2, and v₁. (d) Build the momentum balance for the control volume. Find the force exerted to the hand by using p, d1, d2, v1, v2, P1, and P2.
