Question

Indian tube is lowered into a water stream the velocity of the stream relative to the tube is 20.5 cm per second the closed upper end has a small orifice and it is a height of 1200 m what height does the water spout

Answer 1

Solution :

                   According to Bernoulli's theorem, h=\frac{{{v}^{2}}}{2g}                   \Rightarrow h=\frac{{{(2.45)}^{2}}}{2\times 10}=0.314=31.4\ cm                    \ Height of jet coming from orifice                     = 31.4-10.6=20.8\ cm
