A fire nozzle is coupled to the end of a hose with inside

diameter D 5 75 mm. The nozzle is smoothly contoured and

its outlet diameter is d 5 25 mm. The nozzle is designed to

operate at an inlet water pressure of 700 kPa (gage).

Determine the design flow rate of the nozzle. (Express your

answer in L/s.) Evaluate the axial force required to hold the

nozzle in place. Indicate whether the hose coupling is in

tension or compression.
