Question

An l shaped tube with asmall orifice is held in a water stream as shown. Height of jet of water above the upper end of the tube

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
