A bent tube is lowered into a water stream as shown in figure. The velocity of the stream is `V_(1)`. The closed upper end is located at a height `h_(0) ` and has a small orifice. To what height `h` will the liquid get spurt?

At maximum height total energy will be potential,
Apply Bernoulli's theorem, we have
`(1)/(2)rhov^(2)=(h+h_(@))rhog`
`rArr h=(v^(2))/(2g)-h_(@)=((2.5)^(2))/(2xx10)-0.12` [`g=9.8m//s^(2)`]
`~~20cm` (approximately)
