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 \(v=2.5 \mathrm{~m} / \mathrm{s} .\) The closed upper end of the tube located at the height \(h_{0}=12 \mathrm{~cm}\) has a small orifice. To what height \(h\) will the water jet spurt?

Reveal Answer
h=1/2v2/gh0=20 cmh=1 / 2 v^{2} / g-h_{0}=20 \mathrm{~cm}
