Given:
Height of water in the tank, h = 12.8 m
Gauge pressure of water,
Solution:
Now,
Atmospheric pressue,
At the top, the absolute pressure,
Now, the pressure at the bottom will be equal to the atmopheric pressure,
The velocity at the top, , l;et the bottom velocity, be
.
Now, by Bernoulli's eqn:
where
Density of sea water,
