Text Solution
Verified by ExpertsThe correct answer is:
C
Let tube's entrance be at depth y below the surface.
Take point 1 at entry, 2 at the maximum height of the fountain. Applying Bernoulli's theorem,
… (i)
Taking, 
, 
Hence, pressure term on both sides are equal to atmospheric pressure.
Substituting these values in Eq. (i), we get
