Question
Transcribed Image Text: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.
