A tap discharges water evenly in a jet at a velocity of 2.5 m/s at the tap outlet, the diameter of the jet at this point being 15 mm. The jet flows down vertically in a smooth stream. Determine the velocity and the diameter of the jet at 50-cm below the tap outlet.
A ball weighing 1 kg is “floating" on a circular jet, as shown in the figure
(ignore the wire, which is there to stabilize the weight). The jet leaving the orifice at
the bottom has an upward velocity of 10 m/s, and the jet diameter at the exit is 2 cm.
Assuming the jet spills sideways at 90°, find the height h at which the ball will float.

The pressure inside the rocket is 100 kPa gage. The exit area is one-tenth of the chamber crosssectional area. The inside diameter of the rocket is 5 cm.
