A bent tube is lowered into water stream...

A bent tube is lowered into water stream as shown in figure. The velocity of the stream relative to the tube is equal to `v=2.5m//s`. The closed upper end of the tube located at a height of `12cm` has a small orifice. To what height `h` will the water jet spurt ?

Text Solution

Verified by Experts

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)
