The following figure shows a nozzle connected to a pipe in which
water is conveyed at a pressure P₁=2.875 bar. The fluid undergoes a
constriction: its section S₁ (disc) of diameter d₁=20 mm (0.02 m)
is reduced to an outlet section S₂ of diameter d₂=10 mm. It is
assumed that the fluid is perfect and the nozzle is in a horizontal
position. We give the density of the water ρ =1000 kg /m³ and the
outlet pressure P₂=Patm=1 bar. Reminder: 1 bar = 10⁵ Pa Determine
the ratio of the two speeds V₂/V₁.
