Problem 1.320

A bent tube is lowered into a water stream as shown in Fig. 1.83. The velocity of the stream relative to the tube is equal to v=2.5 m/s.v=2.5 \mathrm{~m} / \mathrm{s} . The closed upper end of the tube located at the height h0=12 cmh_{0}=12 \mathrm{~cm} has a small orifice. To what height hh will the water jet spurt?

Reveal Answer
h=1/2v2/g−h0=20 cmh=1 / 2 v^{2} / g-h_{0}=20 \mathrm{~cm}
