A rigid hose is carried on a buggy and is put into seawater (p=2 slugs/ft^3) to spray seawater onto the

walls of yachts to remove algae.

The crew inserts the hose intake 6 ft below the surface of the water.

You can assume that the hydrostatic pressure at the intake depth in sweater is equal to the pressure if

the intake.

We are told that the weight of all the water in the hose system is 550 lbf

D₁ = Diameter of intake = 2 ft

D₂ = Diameter of outflow = 1 ft

The velocity at outflow = 65 ft/s

Pressure at outflow = Atmospheric (free jet)

Flow is in steady state

Angle = 42°
