Example 4
The sketch shows air flowing through a nozzle. Th e inlet
pressure is p₁ = 105 kPa abs, and the air exhausts into the
atmosphere, where the pressure is 101.3 kPa abs. The nozzle
has an inlet diameter of 60 mm and an exit diameter of 10 mm,
and the nozzle is connected to the supply pipe by flanges.
Assume the air has a constant density of 1.22 kg/m³. Neglect
the weight of the nozzle.
Find the force required to hold the nozzle stationary.
